Task execution isn't idempotent on task's commandLine

build.gradle

plugins {
	id 'com.github.jlouns.cpe' version '0.5.0'
}
ext.testCmd = {
  println tasks['test.cpe'].commandLine
}
task('test1') {
  doLast() { testCmd() }
}
task('test.cpe', type: CrossPlatformExec) {
  dependsOn 'test1'
  commandLine(['bundle', '--version'])
}
task('test2') {
  dependsOn 'test.cpe'
  doLast() { testCmd() }
}
