Build aborted because of an unexpected internal error - Different JDK for sub projects


(Thierry De Leeuw) #1

Hi,

I am trying to build a poject with subprojects using gradle 1.1. Some subprojects should be compiled with a specific JVM (we must support multiple app servers and I want to have all classes compiled against Sun/Oracle JVM, but the specific jars compiled with the JVM of the App Server)

I have a sample code where I have in the root a project including 2 subprojects p1 and p2.

When my JAVA_HOME is set to /opt/jdk1.5.0_22/ and gradle.properties of the root project has the same java.home (org.gradle.java.home=/opt/jdk1.5.0_22/) or no java.home specified, everything works fine.

However, as soon as I change the gradle.properties of the root project to indicate that the project needs t use the IBM jvm for example (org.gradle.java.home=/opt/ibm/WebSphere/ProcServer7/java/), I receive the following exception: java.lang.NullPointerException

Note that 2 daemons are started (one with jdk 1.5 and another one with WebSphere)

Note it also looks like the gradle.properties seems to be ignored when placed in a subproject. To demonstrate this I ran the build with daemons, and I seek that only one daemon is started. I also see that the compiled classes do not reflect the JDK version (one should be compiled with JDK 5 and have version 49, and the other should have version 50)

I can provide you test scripts and extra informaition if needed.

Thanks!

Thierry

A Gradle build runs in one and only one Gradle daemon (not to be confused with compiler daemon), so only the ‘org.gradle.java.home’ property in the top-level ‘gradle.properties’ should take effect. How did you verify that two daemons get started? (They could be from different builds.)

To compile different subprojects with different compilers, you should set ‘tasks.withType(Compile).compileOptions.forkOptions.executable’. Note that you don’t necessarily need to use different compilers to target different JVMs and class versions - instead you can set ‘project.targetCompatibility’.

The NPE sounds like a bug. Can you provide a reproducible example?


(Thierry De Leeuw) #3

Hi Peter,

Thanks for the fast reply.

I will try to set the forkOptions and come back to you.

The reason why I want to compile with the actual JDK is that even if you specify target 5.0, when you compile with a JDK 6, you still have access to the rt.jar of JDK 6 (so if one uses a new class specific to JDK 6, it will compile fine, but when executed on a “real” JDK 5, NoClassDefFound will be reported). If I compile everything against JDK 5 to avoid the previous problem, then the projects that run on JDK 6 would not be able to use the new classes from the JDK 6 rt.jar.

Here is what I get when JAVA_HOME=/opt/ibm/WebSphere/ProcServer7/java and gradle.properties

org.gradle.daemon=true org.gradle.java.home=/opt/jdk1.5.0_22/

I get the following error:

:p1:compileJava

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ‘:p1:compileJava’. > javax/tools/ToolProvider

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Note: that the daemon is running with JDK 1.5 and the actual exception is NoClassDefFound (see end of the post)

if in the main project I change the settings to org.gradle.java.home=/opt/ibm/WebSphere/ProcServer7/java, the projects are build successfully (the daemon is IBM one).

If now I change my JAVA_HOME to jdk 1.5 (and keep the org.gradle.java.home=/opt/ibm/WebSphere/ProcServer7/java) I have the null pointer exception (see at the end of the post for full stack trace)

Note that I could not get the 2 JVM running at the same time, so indeed, I must have forgottent to stop the daemon at one point…

So it looks like if I have a different JDK than the one specified in the config I either have a NoClassDefFound or a NPE depending on the JVM used.

How can I send you my test project?

Thanks!

(Peter Niederwieser) #4

As an alternative to using a JDK5 compiler, you could also cross-compile against JDK5.

The NoClassDefFoundError is suprising. It means that although Gradle thinks it’s running JDK6+, the ‘javax/tools/ToolProvider’ class isn’t available. Not sure how this could happen.

To just share your build script(s), you can use a service like https://gist.github.com. The smaller the project, the better. To share a zip, you’d have to upload it somewhere, as this forum doesn’t support attachments.


(Thierry De Leeuw) #5

Hi,

Please find here the download to the gist containing all the files https://gist.github.com/gists/3419622/download or git://gist.github.com/3419622.git

the fork option is working fine for compile, but not so well for the JUnit tests - some jar delivered with WebSphere 7 are compile against JDK 6, whcich prevent me to run them with JDK 5

Thanks for your help !


(Peter Niederwieser) #6

The fork option doesn’t affect tests. Unless you set ‘test.executable’, tests will be executed with the JDK that’s used to run Gradle,


(Thierry De Leeuw) #7

I was looking for a fork and friends in the options of the “test” task (as for the compileJava task) but didn’t found anything there, so I [wrongly] assumed it was not possible (I didn’t paid attention to the executable parameter.)

Thanks!
