Setting task inputs and outputs always gives UP-to-Date

[k4rn4k]

Hello,

Im setting this task outputs like shown in the user guide, but It's always
being resolved as "up to date as it has no source files".

task buildExplodedWar(type: Copy)<<{
//Configuring inputs/outputs
destDir = new File ("$project.buildDir/war")
project.configurations.runtime.each{srcFile ->
inputs.file srcFile
}
outputs.dir destDir
//Some copy behaviour
}

The problem is that you are setting them during task execution.

You need to rewrite as this:

task configureBuildExplodedWar << {
project.configurations.runtime.each { srcFile ->
buildExplodedWar.from srcFile
}
}

task buildExplodedWar(type: Copy, dependsOn: configureBuildExplodedWar) {
destination "$project.buildDir/war"
}

That should be all you need.

This is somewhat of a general pattern for delaying task configuration until execution, that we call “configuration tasks”.

}

Or even just

task buildExplodedWar(type: Copy) {
from configurations.runtime
destination "$project.buildDir/war"
}

Ha, indeed. Forest for the trees.
