Hey @xbradleyhunterx. I raised this Gradle enhancement request the other day. It is related to that one „extraneaous command-line arguments“ problem you reported a while back for your use case.
Maybe if enough people vote for it, Gradle devs might do something about it at some point.
Did you ever figure out how to make Gradle not add those stupid system properties, by the way?
Bug Fixes in v0.0.13
:jar task began reporting „Skipping task ‘:jar’ as task onlyIf is false“ for some reason. Code changes in the applying project weren’t being bundled as expected — FIXED
Heads up
apply false in the root project like this… plugins{
id 'com.lingocoder.mrjar' version '0.0.13' apply false
}
...
subprojects{
...
}
…breaks mrJar. The root project needs to do this instead…
plugins{
id 'com.lingocoder.mrjar' version '0.0.13'
}
...
subprojects{
...
}
Surprisingly, projects with the precise same hierarchical structure — but use allprojects instead of subprojects — work perfectly fine with apply false.
If anybody can please share their knowledge of the general conditions under which apply false might cause problems in multi-projects, I’d be sincerely grateful. TIA.
I can’t thank the gradle-module-plugin project often enough. So thanks again @tlinkowski, @siordache, et al. You guys’ ModulePluginSmokeTest passing with flying colors with mrJar applied to your project, gives me boatloads of confidence that mrJar is in at least reasonable shape for a minimum viable product 
Another concern that @chrisdennis expressed in Gradle issue #10046 was: „I’m not sure I can trust [mrJar] when I need to run it on privileged machines“.
I wasn’t sure myself. So I did a scientific, totally objective experiment in which I ran the mrJar JAR through 57 different virus scanners. I also ran mrJar through an OWASP security analyzer as part of the build for v0.0.13’s demo project .
I’m sharing the results of my experiment for open peer review.
For what it’s worth: I’m sharing this because (a) I think it’s interesting data in its own right (b) Sharing any security analysis data is always the responsible thing to do, in my opinion.
The good news is that mrJar got a clean bill of health!1 The not-so-good news is that tons of people are using dozens of third party open source dependencies that have known security vulnerabilities. And „on privileged machines“ no less.
Who knew that Gradle had so many security issues? That was a huge surprise to me! 
Ironically, the dependency-check plugin flagged itself as having security vulnerabilities! How’s about that for objectivity and full disclosure?
But as the saying goes: „Nullius in verba“. Anybody could repeat for themselves the same experiment I did. They’d get the same results. Just download that above-linked v0.0.13 demo project and run the :repeatExperiment task from that project’s authn folder. If your Gradle’s cache has any of the same files in it that mine did at the time, then you should see that the hashes are the same for the same artifact.
Oh! And please share your results of your own dependency check experiments? TIA
1 — Of course, mrJar wouldn’t be in NIST’s NVD because (a) NIST don’t have the source code. And (b) nobody but me’s using mrJar anyway 
No biggie @Graou74. That Eclipse script I shared with you, I’ve been using in Visual Studio Code a lot for the past several months. So out of habit I add it to every new project I create. I’d actually forgotten that I’d bundled it into that one project I’d uploaded for you until the next day.
It is a hassle to copy a script into every new project. Isn’t it? So I went ahead and incorporated Eclipse/VS Code plug-and-playability into mrJar v0.0.14. So using VS Code/Eclipse should be a little less of a pain in the butt for me with this.
There are three ways to modulfy Eclipse with this new mrJar feature. Here’s a video showing the main way that I prefer to use it myself:
First — before I import my project into VS Code (which is really just Eclipse-lite) — I apply the mrJar plugin to my build.gradle…
plugins{
...
id 'java-library'
id 'eclipse'
id 'com.lingocoder.mrjar' version '0.0.14'
...
}
Then I import the existing Gradle project like normal
That’s all there is to it! Eclipse has now been modulefied!
Or it’s also possible to modulefy an existing VS Code/Eclipse project. Doing it that way, there are two options:
:eclipse task like normal (after applying mrJar inbuild.gradle, of course)Feel free to try mrJar out for yourself, @Graou74. In addition to this new Eclipse module enabling feature, release v0.0.14 also fixes a bug I discovered the other day.
Hello Lingocoder,
I just tried the mrjar plugin on a new project but I have the following trace to the “Refresh Gradle Project” (I filled in the builkd.gradle the task “plugins” with “id ‘com.lingocoder.mrjar’ version ‘0.0.14’”):

Hey thanks for the feedback @Graou74! Apologies for the delayed reply. I was pretty engrossed in something else and couldn’t break away to check in on the forum until now.
So sorry. That was a failed experiment with a private remote repository to host some support libraries. Turns out it was too private. To where mrJar worked only on my machine. I hate when that happens! 
But I’ve deleted the private v0.0.14 from Gradle’s plugin repository, and just now replaced it with the fully-working public v0.0.15. Would love to get more feedback from ya, Graou74! TIA 
No problem 
, you have already given me a satisfactory solution and even if it would be very rude on my part to demand anything.
We do the same job (so we are never safe from surprises) and if Gradle contributes to the robustness of a product, we see that little misery of development can still infiltrate.
I commented out all the code for the eclipse task and inserted the “id” com.lingocoder.mrjar “version” 0.0.15 “” line into the plugins task :
plugins {
// Apply the java-library plugin to add support for Java Library
id 'java-library'
id "com.lingocoder.mrjar" version "0.0.15"
}
repositories {
// Use jcenter for resolving dependencies.
// You can declare any Maven/Ivy/file repository here.
jcenter()
}
dependencies {
// https://mvnrepository.com/artifact/org.yaml/snakeyaml
compile group: 'org.yaml', name: 'snakeyaml', version: '1.25'
testImplementation('org.junit.jupiter:junit-jupiter-api:5.4.2')
testRuntime('org.junit.jupiter:junit-jupiter-engine:5.4.2')
}
compileJava {
doFirst {
options.compilerArgs = [
'--module-path', classpath.asPath,
]
classpath = files()
}
}
//apply plugin: 'java'
//apply plugin: 'eclipse'
//
//eclipse {
// classpath {
// containers 'org.eclipse.buildship.core.gradleclasspathcontainer'

// it.entryAttributes['module'] = 'true'
// }
// entries.findAll { it.properties.path.startsWith('org.eclipse.jdt.launching.JRE_CONTAINER') }.each {
// it.entryAttributes['module'] = 'true'
// }
// entries.find { it.path == 'src/main/java' }.output = 'build/classes/java/main'
//
// def testSrc = entries.find { it.path == 'src/test/java' }
// testSrc.output = 'build/classes/java/test'
// testSrc.entryAttributes['test'] = 'true'
// testSrc.entryAttributes['optional'] = 'true'
// testSrc.entryAttributes['ignore_optional_problems'] = 'true'
//

In Eclipse, everything works perfectly, unfortunately when I run the command line test I have this error (error that does not exist with the code of the eclipse task):

I do not understand why it talks about the module “ExternalParam” which has been renamed to “com.ondine.ExternalParam”.

The org.junit.jupiter.api module will be read

Here are the occurrences of the word “External Param” in the project:
Thanks again @Graou74.
Just a heads up, @Graou74. You don’t need to do that. mrJar is doing that for you already under the hood. That’s sort of the main thing it does as a plugin. Though I don’t think it hurts anything to override what the plugin does. It’s just not strictly necessary.
Ah! You discovered the other thing I was engrossed in working on before I logged into the forum yesterday.
I was in the middle of implementing some new core functionality, then commented out most of it so that I could push the changes for the other fix quicker. In my haste I left that half-way finished code in there.
I will look into what might be causing the renaming you’re describing. If you could share a lightweight facsimile of your project, that would be a great help for troubleshooting.
Funny you should say that. The reason I was so engrossed in the other thing I mentioned, is because Gradle’s „robustness“ was causing me misery 
As marvelous as Gradle’s contributions are to Java development in general, they do throw up some frustrating hurdles for JPMS development — in particular.
A super skim version that reproduces the problem :
ExternalParamLite.zip (90.2 KB)
I deleted the build directory which takes up space and will be rebuilt anyway.
Cool! Thanks @Graou74
Sorry I didn’t spot this earlier…
You need to add this…
mrjar{
moduleName = 'com.ondine.ExternalParamLite'
}
That worked when I tried it…
There’s a mrJar usage page that might be useful (I should have read it myself earlier, actually, with my memory 
). Some of the more recent changes and added capabilities haven’t been documented there yet. But the most important core parts are still relevant.
Please, don’t hesitate to reach out if anything else breaks for you using mrJar? TIA
Now everything works perfectly. 
Again thank you Lingocoder for your help.
That’s great, man! As a token of appreciation, I’ll share a little tip with you. Notice in your original error message, that your search found the different occurrences of the word „ExternalParam“? Well if mrJar isn’t given a value for its moduleName property, then it will use this value as a default whenever it needs a moduleName but can’t find an explicitly-defined one…
That means that instead of setting the moduleName property in the mrjar{ } extension block, you could also have changed the name of your project to be the same name as that in your module-info.java descriptor.
In addition to also fixing the error the same as setting an explicit property, that option also makes for three or four fewer lines in your build.gradle.
Exercising mrJar with your project these last couple days, Graou74, has introduced me to some new usage scenarios that had not occurred to me with my automated functional testing. So I am sincerely grateful for your helping me work out some previously-undiscovered kinks in the code. Many thanks to you, man!
Immediately revealed, immediately adopted.
I did not see it like that. From my point of view, only you helped me.
Now I can devote myself to a new problem which is how to access with Gradle packages of modules not exported.
I would like to violate JavaFx which lacks openness in places.
Hi @Graou74
That sounds like an interesting problem. Please can you share what your solution for that was in the end? TIA
Hi Lingocoder,
I did not find a solution in JPMS. So I abandoned the idea of developing an application in modules. I do not develop a utility or a library so putting the programming module aside is less serious.
At each step of setting up the architecture are hours of research to make the various development tools work together (Eclipse, Gradle, JavaFx, AspectJ etc) while without JPMS just load an Eclipse plugin and it is set.
I understand the usefulness of a modular development but the extra layer on access to the packages, justified as a reinforcement of object concept, had no other effect than to rot my life.
I have tried, but the time I have devoted to this research is a luxury that I can not afford.
Since I have set aside the JPMS development I can devote my time to development and advance my application.
So to conclude the solution was for me to forget the modular development and load a Gradle plugin for JavaFX.
