Seemingly trivial additions to build.gradle cause _BuildScript_ error

David_Karr · October 10, 2017, 5:05pm

Gradle Version: 4.2
Operating System and JVM version: Win7, 1.8.0_102
Eclipse: 4.7.1
Buildship: 2.1.2

I’m seeing an odd situation where a perfectly working build.gradle gets trivial and valid changes made to it, and executing “Refresh Gradle Project” gets a very strange error in Buildship, even though the project still builds fine from the command line in all variations of this test.

I’m not going to include the original script at this time, because I have a feeling it’s irrelevant. In my current test case, I simply added the following to the end of the file (from my testing, I doubt it really has anything to do with the contents of what I’ve inserted):

task wrapper(type: Wrapper) {
    gradleVersion = '4.2'
}

And when I do “Refresh Gradle Projects”, I see this in the console:

FAILURE: Build failed with an exception.

What went wrong:
A problem occurred configuring root project ‘springbootgradleproto’.

Could not create an instance of type build_dfevob548w5lmgtcv8qfq8geu.
BuildScript

I then removed the added task and re-refreshed, and it worked perfectly fine.

I then made a different unrelated and valid change, simply adding an entry to a string list that an “each” call was being made on, and the refresh reported about the same error (I didn’t note whether the tail of “build_” was the same).

In addition to the info in the console, it presents the following stacktrace in a dialog:

I’ve even tried restarting Eclipse, and that didn’t seem to make any difference. I still get the same error after I change the script. Changing it back to the original makes it work again (but of course, that leaves me with no ability to make any changes to the script).

David_Karr · October 10, 2017, 7:38pm

Ok. This is a Groovy problem (at least). I realized that my groovy plugin was set to use groovy 2.5.0 beta. I changed it to 2.4.12 and restarted, and then I was able to process my Gradle build.

st_oehme · October 11, 2017, 10:57am

The only far-fetched explanation I’d have for this is that Groovy-Eclipse is deleting the compiled build script from Gradle’s cache, therefor breaking the daemon which of course assumes its caches to not be edited by other tools.

I get this one kind of often. System details as follows:

Gradle version: 4.2
OS Windows 10 professional v1703
Eclipse 4.7.1a
Buildship 2.1.2

The plugins applied to my project are java, application, findbugs, and pmd, so I’m not sure if Groovy versions are applicable to it. Also, I get the same error when trying to run commands with gradlew on the command line, completely independently of Eclipse. Something simple like adding an extra newline somewhere will sometimes make it work, and then deleting the line will cause it to break again. Killing daemons with gradle --stop doesn’t seem to help either, and neither does disabling it with org.gradle.daemon=false in gradle.properties.

I kind of thought that it might be something to do with me constantly running Gradle tasks from both Eclipse, and the command line. Like, they might be interfering with each other?

Here’s an example stacktrace from running a task from the command line:

C:\XXXXXXXXX>gradlew tasks --stacktrace --no-daemon

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'XXXXXXXXX'.
> Could not create an instance of type build_c59edbyudnxl22wx772vah6m0.
   > _BuildScript_

* Try:
Run with --info or --debug option to get more log output.

* Exception is:

BUILD FAILED in 2s

I’ve been having this problem. I took out the big hammer and hit a fairly simple solution. From your project directory:

rm -rf gradle .gradle gradlew*
gradle wrapper

And the problem went away. I’m going to provide more info.

I’ve been trying to import projects into Eclipse. Eclipse was installing a Gradle Wrapper version of 3.5. I have the latest Gradle of 4.2.1 (as I’m writing this). But Eclipse created a .gradle directory with a 3.5 installation.

I could hit the problem with a simple gradlew tasks.

My fix may be a bigger hammer than necessary, but after doing it, gradlew tasks actually works, and I can import the project into Eclipse.

Thanks for the reply, that’s interesting. In my case, deleting the .gradle directory and wrapper doesn’t seem to help – even running the gradle wrapper task fails with the same error. I upgraded my Gradle version to 4.3-rc-3, and then it worked first time (on a script that wasn’t working before), but then after making further changes to the build script, it failed again.

So eventually, I went and deleted [gradle user home]\caches\4.3-rc-3, and that seemed to help for the moment…

EDIT: It doesn’t always help. It seems like I need to delete that cache, then run a gradle task from the command line, and then it will work. If I delete the cache and then immediately try to refresh the project in Eclipse, it breaks.

The problem was not with the Groovy plugin for Gradle, but the Groovy plugin for Eclipse. Can you check which plugins you have installed in Eclipse?

arihunta · October 26, 2017, 11:35am

Ah, right! I only very recently installed Groovy-Eclipse, and I think I’ve only been getting this error since then. It seems to update itself almost every day. According to the Eclipse Marketplace, I had Groovy-Eclipse for Indigo 2.7.1 and Groovy-Eclipse for Juno 2.7.1 installed. Under “Help -> About Eclipse -> Installation Details”, the following versions were displayed:

So, I reverted my Eclipse to before I installed those plugins, and it seems to have fixed this issue. Thanks for the help!

st_oehme · October 26, 2017, 11:56am

Thanks for verifying! @donat I think we should tell the Groovy-Eclipse team that their 2.5.0 release is breaking Gradle. Seems they are somehow deleting classes from our compiled script cache.

donat · November 6, 2017, 8:18am

Done: https://github.com/groovy/groovy-eclipse/issues/370

st_oehme · November 6, 2017, 6:11pm

@David_Karr @arihunta The groovy-eclipse team might need your help to find the issue. They currently have no idea why it would be interfering with Gradle’s cache. But since downgrading it fixed the issue, there must be some connection.

ramonmartinl69 · March 5, 2018, 9:01am

In my case it Worked deleting inside USER_GRADLE_HOME .gradle/deamon/* .gradle/caches/*, inside WORKSPACE_ECLIPSE project .gradle, gradle, gradlew and finally do a ‘gradle wrapper’
