Hi,
I am building ovirt-engine 3.6.4.1 and failed with NullPointerException. I build for cross compile with commands:
tmp_repo=/buildarea3/kkang/builds/Mar31-ovrit-engine/bitbake_build/tmp/work/corei7-64-wrs-linux/ovirt-engine/3.6.4.1-r0/repo export MAVEN_OPTS="-Dmaven.repo.local=$tmp_repo"

The error messages show:
[INFO] oVirt Engine API Definition ....................... FAILURE [1.476s] ... [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:java (default) on project restapi-definition: An exception occured while executing the Java class. null: InvocationTargetException: NullPointerException -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:java (default) on project restapi-definition: An exception occured while executing the Java class. null at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:216) ... at javax.xml.bind.JAXB.marshal(JAXB.java:332) at org.ovirt.engine.api.rsdl.RsdlManager.serializeRsdl(RsdlManager.java:134) at org.ovirt.engine.api.rsdl.RsdlManager.generateRsdlFile(RsdlManager.java:84) at org.ovirt.engine.api.rsdl.RsdlManager.main(RsdlManager.java:58) ... 6 more
My questions are:
1 I know the error occurs in file backend/manager/modules/restapi/interface/definition/src/main/java/org/ovirt/engine/api/rsdl/RsdlManager.java, but how to debug it?
2 When I remove pom and jar files of javax.xml.bind.JAXB in mave repo with offline mode, it still could find the class. Which javax.xml.bind.JAXB is used? I searched the ovirt engine repo but didn't find it either.
The version of JAXB used by that area of the code is the version of JAXB included in the JDK that you are using for the build. So the question is what version of the JDK are you using? -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg.
