Compile JasperReports with Gradle gets unsupported version error
Recently i implemented a new builder with gradle runs on jenkins. Our project contains jasper reports so i added below task to compile jasper reports with an ant task which is supplied by jasper reports api.
task compileJasper {
println "############# Compiling JasperReports in Projet $project.name ###################"
def jasperSourceDir =sourceSets.main.java.srcDirs[0]
def jasperTargetDir = sourceSets.main.output.classesDir
def classPath = ant.path {
fileset(dir: "JarLib/", includes: '**.jar')
}
ant {
taskdef(name: 'jrc', classname: 'net.sf.jasperreports.ant.JRAntCompileTask',
classpath: classPath)
jasperTargetDir.mkdirs()
jrc(srcdir: jasperSourceDir, destdir: jasperTargetDir) {
classpath(path: classPath)
include(name: '**/*.jrxml')
}
}
}
Everything is fine with compiling and works as expected but after deploying project to server, at runtime getting the following error.

We use websphere 8.5 for runtime with java 1.6 . This is java -version output
/opt/IBM/WebSphere/AppServer/java/bin/java -version java version "1.6.0" Java(TM) SE Runtime Environment (build pxa6460_26sr8fp2ifix-20141114_01(SR8 FP2+IV66608+IV66375+IX90155+IV66944)) IBM J9 VM (build 2.6, JRE 1.6.0 Linux amd64-64 Compressed References 20141114_222464 (JIT enabled, AOT enabled) J9VM - R26_Java626_SR8_20141114_1023_B222464 JIT - r11.b07_20141003_74578.01 GC - R26_Java626_SR8_20141114_1023_B222464_CMPRSS J9CL - 20141114_222464) JCL - 20141005_01
At first time i got the error gradle configured to run with java 1.7.0_51 so i changed gradle java to "java 1.6.03" but nothing changed. Any idea ?
I printed all ant properties with the following code in the ant block.
ant {
for (o in properties)
println o
...
..
.
}
I see that gradle somehow use system default java as java.endoresed.dir property although i set the org.gradle.java.home value to 1.6 in the gradle.properties file.
java.endorsed.dirs=/usr/java/jdk1.7.0_51/jre/lib/endorsed
I ended up the issue with changing the system java version to 1.6. This maybe a gradle bug.
