Gradle setupBuild exception

Old Forum Archive
1

I ran the new setupBuild phase as documented in 1.6-rc-1 on two of my maven projects. This was my first time using gradle and I have no gradle settings of any kind.

One of my maven projects is a reactor build with several modules but simple configuration for each model. The other project is a single project. Unfortunately, I cannot share the exact POM contents. I will try to pair down my POMs until I have a short reproducible example. In the meantime, here is the debug log from the multi-module project. There is a NullPointerException in there:

I’m having the same problem converting my Android-projects. It’s pretty easy to produce, just create a maven android project using the archetype, and try to run setupBuild in that.

See here for example.

3

@Simen I can reproduce your exception when running “gradle setupBuild” on your “archetype” project. The problem seems a bit different than the stracktrace listed by “absurdhero”

4

Oh, I just saw an NPE and the same error, I didn’t actually compare the stacktraces too much.

Shall I create a new issue on this?

5

I’ll do that after finding the root cause of the problem. I’ll ping you once I know more

6

OK, thank you very much for the quick response!

7

I’m seeing the same issue converting an Android project…seems like a bug in Gradle’s setupBuild plugin since the NPE is down in the code that tries to set up a workspace internally in that plugin :frowning:

8

Hello, any updates on this? I’m trying to convert our Maven build to Gradle, using the same task, and I get the same exception:

A fix/workaround would be nice!

I’m just working on that. Is your maven plugin using extensions? It seems, that this is at least one cause of failure here. I’ll ping you when I have a fix in place.

cheers, René

Hi Rene, I’m not sure what you mean with that. You mean something like this? http://maven.apache.org/guides/mini/guide-using-extensions.html

Cause then the answer is no. I’m also not building a plugin, it’s a ‘normal’ project. I checked for any reference to extensions, but it seems to not be there.

I can send you an (obfuscated) pom if you want, but I cannot post it here.

11

Hi eric, yes, that’s exactly what I mean. An obfuscated pom would help me a lot. you can send it to rene.groeschke@gradleware.com.

many thanks,

René

I found that one of my POMs works fine if I remove the section. My parent pom is very simple. When I copy its contents directly into the project, the build also succeeds. It seems to be the use of itself that causes the problem.

I can’t seem to get xml to display in here so here is this post on pastebin: http://pastebin.com/AJVMvLEU

My parent pom looks like this:




  



4.0.0



  com.example



  example



  1.0-SNAPSHOT



  pom







  





 UTF-8



  







  





 







releases







http://corp.repo/content/repositories/releases





 





 







 snapshots







 http://corp.repo/content/repositories/snapshots

and it is being included like this:




  





 com.example





 example





 1.0-SNAPSHOT

I actually tried the same (remove the parents) and now it’s working quite a bit better: at least the build.gradles are generated. That’s a good start. Now I suffer from ‘cyclic variable definitions’ when I try to build my project. Any ideas, or should I start a new topic for this?

14

I guess you run into the problem described here: http://forums.gradle.org/gradle/topics/latest_setupbuild_plugin_fails_with_stackoverflow

At the moment I see too issues with the maven2gradle converter:

  1. it fails with nullpointer if parent pom is declared (havn’t completely verified this issue)

  2. the described stackoverflow seen in the link above.

We fixed GRADLE-2666 which was caused by using external custom maven plugins in your maven build which are not evaluated anymore.

BTW. Eric, you send me a sample mvn build for testing. this mvn build is not working for me as I get the following error message when running “mvn package”

Hi Rene,

For 1, that’s correct. When I move the properties to my child POM, it creates the build.gradle file. But when I try to build it using ‘gradle build’, I don’t get the error as described in your link, I see something like (I don’t have the output here): unable to find reference X, error: cyclic variable definitions : [project.version, project.version].

On Thursday, I can paste the correct error message here, but I haven’t found out what the problem is so far, plus the project is quite big.

Thanks, Erik
