Running a task only when dependencies are changed

Old Forum

In many projects, our classpath exceeds the 32k classpath restriction on Windows. To account for this we created an extra task that creates a jar with the actual classpath in the manifest. I only want to rerun this task when dependencies are changed, otherwise it triggers a full redeploy.

Here’s basically what I have:

  task('compileClasspathJar', type: Jar) {

doFirst {

 def relativeClasspathEntries = sourceSets.main.compileClasspath.collect {

  project.relativePath(new Path(it.getAbsolutePath()))

 }















  manifest {

  attributes "Class-Path": relativeClasspathEntries.join(" ")

 }

}  }

 task('setClassPathJar') {

dependsOn compileClasspathJar

doFirst {

 sourceSets.main.compileClasspath = files(new File(project.projectDir.getAbsolutePath(), 'compile-classpath.jar'))

}  }

Is there anyway to connect dependencies to task inputs?

You should be able to set the source set compileClasspath as an input file collection:

task('compileClasspathJar', type: Jar) {
  inputs.files sourceSets.main.compileClasspath
  ...
}
