OutOfMemoryError during build

[cherimo]

I am using Android sdk 31

When I am trying to build https://github.com/schwabe/ics-openvpn > main. I am constantly get the following error:

Execution failed for task ':main:packageSkeletonOvpn2DebugAndroidTest'.
> A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable
   > java.lang.OutOfMemoryError (no error message)
...
Caused by: java.lang.OutOfMemoryError: Java heap space

After some searching on the internet it seems to adjust the memory size in gradle.properties. I updated the line to: org.gradle.jvmargs=-Xmx8608m

I also adjust the memory file > settings > memory settings > adjusted to 4GB For the record I have more then 60GB of RAM so there should be no problem.But still the errors keeps coming. It doesnt matter how big the memory size is.

Am I missing something?

[schwabe]

I have org.gradle.jvmargs=-Xmx4096M in my own builds. There are some unresolved problems currently with building the unit tests (see also the github actions) but I see different errors. Does ./gradlew assemble also fail for you?

Also note that for the Android Studio I currently are running the preview version to have Android 14 support.

[cherimo]

I Installed the latest Java and somehow when I open the folder "main" in Android studio and start "Make module..." then the build is succesfull somehow. But when I view the build folder I only see some Json files in "main\build\intermediates\cxx".

Yes "./gradlew assemble" in "ics-openvpn" does fail. It returns unresolved problems:

[schwabe]

That sounds like you are running with Java 8. The build require Java 20.

[syphyr]

That sounds like you are running with Java 8. The build require Java 20.

Do you mean Java 17? https://github.com/schwabe/ics-openvpn/blob/00741018908217663dc85104c5ddf708d1e3a952/main/build.gradle.kts#L143

[schwabe]

No. I actually mena Java 20. Source code compatibility is 17 but there are some components of gradle version or android build system that actually require Java 20 iirc. Nevertheless, I run the build with OpenJDK 20, so you might need to do the same.

[syphyr]

Just tested building master branch with openjdk 17.0.8 and everything works.

[cherimo]

I installed the latest java:

When I clean everything up and tried the following command "./gradlew assemble" on folder "ics-openvpn" I get the following error:

Just tested building master branch with openjdk 17.0.8 and everything works.

I tried to build the module with the following java(x64) : https://learn.microsoft.com/en-us/java/openjdk/download#openjdk-17 But still no luck.

I am gonna try it on my Linux Ubuntu(22.04) machine and see what the results are going to be.

[cherimo]

Unfortunately I am getting the exact same error on my Ubuntu 22.04 machine. I will post below the stack trace and my settings that I am using.

Is there maybe a step that I'm missing?

[schwabe]

you seem to have modified the build.gradle. That does not make debugging/comparing against my setup easier. I would suggest running the working task assembleUiOvpn23Release from the unmodified repository. That also works in the the github actions that do not depend on special environment my own build environment might have.

[cherimo]

@schwabe My apologies I have restored the file to its original state as it is here: https://raw.githubusercontent.com/schwabe/ics-openvpn/master/main/build.gradle.kts

Apart from Gradle.properties, there are no other files that have been modified.

I cleaned the project and tried again this time its packageSkeletonOvpn2Debug instead of packageSkeletonOvpn2DebugAndroidTest:

Execution failed for task ':main:packageSkeletonOvpn2Debug'.

> Run with --scan to get full insights.

[syphyr]

For gradle.properties, try just this: org.gradle.jvmargs=-Xmx2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

[syphyr]

Also, I'm not sure if you tried this already, but try building without android studio in just a terminal.

[cherimo]

@syphyr Have applied both setting and tested the CLI command. In both cases outofmemory :/

I'm really bamboozled I've tested other clones from other apps and they all seem to work but specifically ics-openvpn doesn't seem to work.

I literally ran and tested the following commands and it still get outofmemory.

$ git clone https://github.com/schwabe/ics-openvpn.git
$ cd ics-openvpn
$ git submodule init
$ git submodule update
$ ./gradlew assemble

Results:

* What went wrong:
Execution failed for task ':main:packageSkeletonOvpn23Debug'.

   > A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable

   > A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable
      > java.lang.OutOfMemoryError (no error message)

I'm going to troubleshoot my memory even though I don't see a spike in my memory when I build. There is a limit/bug somewhere that doesn't seem to work properly.

[schwabe]

I know that the build is problematic and that it not always works but the github actions are now happy again with the build instructions (https://github.com/schwabe/ics-openvpn/blob/master/.github/workflows/build.yaml) that do not contain much special stuff.

[EliyahuSternDAI]

@schwabe If java 20 is required, I suggest adding the following to main/build.gradle.kts: java { toolchain { languageVersion.set(JavaLanguageVersion.of(20)) } } It's also possible to specify Download Repositories so that the JDK is automatically downloaded and used by Gradle.

[EliyahuSternDAI]

FYI I'm getting OutOfMemory javaHeapSpace when using Amazon JDK, and not when using Azul/ZULU or AdoptOpenJDK.

[schwabe]

@EliyahuSternDAI check the github actions, they use JDK 17 and run just fine with it. I am using JDK 20 on my own dev machine.

[EliyahuSternDAI]

@schwabe woks fine for me as well. I still think that specifying the version+vendor in Gradle can be a good idea. Especially as some JDKs cause memory issues.

[schwabe]

@EliyahuSternDAI different school of thought. But the github actions show at least one working JDK that can be used. I will close the issue for now as this issue is not really getting anyway.
