Problem with jar that contains java sources


(Cyrill Zadra) #1

My java project depends on other jar files that contains java classes and its sources. When i compile my project it always tries to compile the java source files from the jar file. Is there a way to prevent gradle from compiling the source files in the jar?


(Peter Niederwieser) #2

Can you provide more information, including your build script? Gradle won’t do that normally. I think you’d even have to unjar the sources to make it “work”.

Hi

Yes of course… here my build.gradle. The iengine.jar file contains the java classes and sources. When I manually remove the java sources in the jar I can build my project otherwise it throws “not found exception” from the java files in the jar file.

apply plugin: ‘java’ version = ‘1.0’ sourceCompatibility = 1.5 jar {

manifest {

attributes ‘Implementation-Title’: ‘JaxWS Dynamic Client’, ‘Implementation-Version’: version

} } sourceSets {

main {

java {

srcDir ‘src/main’

}

}

test {

java {

srcDir ‘src/test’

}

}

}

repositories {

mavenCentral()

ivy {

name = ‘ivyRepo’

artifactPattern “file://172.16.15.237/Share/Software/i-engine/ivy-repository/[organisation]/[module]/[type]s/[artifact]-[revision].[ext]”

} }

dependencies {

compile(ivyDependencies(‘compiletime->default’))

compile files(‘lib/iengine.jar’) }

def ivyDependencies(conf) {

def dep = []

def ivyModule = new XmlParser().parse(file(“ivy.xml”))

ivyModule.dependencies.dependency.each {

if(it.@conf == null || it.@conf == conf)

dep.add(it.@org + ‘:’ + it.@name + ‘:’ + it.@rev)

}

return dep }


(Peter Niederwieser) #4

Can you post the Gradle build output too, including the error message(s)? Not sure what’s happening here. It’s not uncommon for Jars to contain the source code, but I’ve never seen it cause a problem.

Hope this output helps. gradle output with --info argument.

One possible thing to check is the timestamps of the sources vs. the classes in the jar. If the sources are newer than the classes, then javac will try to recompile them. We ran into this in our Ant build system…


(Cyrill Zadra) #8

Yes the sources are 1 sec newer then the classes… :slight_smile: … How did you solve it… unjar the jar and remove the source files?


(carl.quinn) #9

In our case, the sources were from our own builds, so I made sure that they had their original timestamps when we jarred them. You could process the jars and set the timestamps for all sources to effectively 0, somewhere back in 1980 when DOS began. They would still work as source for IDEs, but the dates would be old and would never bother javac.
