Sort of. You can do the same sort of thing by instead injecting the jars into
the Ant classloader from the build script. Here's an example:
configurations {
jdt
}
dependencies {
jdt "org.eclipse.jdt:ecj:3.5"
}
compileJava {
options.compiler = "org.eclipse.jdt.core.JDTCompilerAdapter"
doFirst {
ClassLoader antClassLoader =
org.apache.tools.ant.Project.class.classLoader
configurations.jdt.each { File f ->
antClassLoader.addURL(f.toURI().toURL())
}
}
}
I'm curious why you want to use the eclipse compiler, if you don't mind me
asking?
