I don't think trying to do configuration in response to a resolve event is a
good approach to configuration - it doesn't describe the dependency between the
task and its configuration logic very well. I think the solution to the above
problem would be to use a (regular) configuration task that executes before the
unpack task:
task configureSdks {
dependsOn configurations.compile
doLast {
configurations.compile.each {
if (it.name.endsWith(".zip") {
unpackSdks.from(zipTree(it) { into it.name - ".zip" }
}
}
}
}
task unpackSdks(type: Copy, dependsOn: configureSdks)
Given that such logic is so common, we should add some convenience methods to
the DSL for this. We've discussed this a bunch of times on this list.
