Failed to apply plugin on project


I am running across an issue applying a build script from a separate lower level folder. I am not using the gradle multi-project functionality intentionally because of configuration ordering problems (namely one project has to run completely before the others can be configured). To work around this I am just using a shared folder with shared gradle scripts.

I have contrived an example to demonstrate the problem:

Directory structure: fixme/ fixme/myproject/ fixme/myproject/build.gradle fixme/shared/ fixme/shared/shared-build.gradle


apply from: "../shared/shared-build.gradle"


buildscript {
 println "Setup buildscript"
    repositories { flatDir name: 'libs', dir: 'C:/gradle/gradle-2.2.1-all/gradle-2.2.1/samples/customPlugin/plugin/build/libs/' }
    dependencies { classpath group: 'org.gradle', name: 'customPlugin', version: '1.0-SNAPSHOT' }
    println "And now I'm here"
project.buildscript.configurations.classpath.each { println it }
buildscript.configurations.classpath.each { println it }
  apply plugin: 'org.samples.greeting'
apply plugin: 'java'

Observe that if the code in shared-build.gradle is in build.gradle everything works fine. I am pulling in a built version of the sample plugin that comes with gradle 2.2.1. However, when build.gradle delegates some of its logic to shared-build.gradle I get this:

C:\view\mrichar2_apr\fixme\myproject>gradle -i build Starting Build Settings evaluated using empty settings script. Projects loaded. Root project using build file ‘C:\view\mrichar2_apr\fixme\myproject\build.gradle’.

  • Where: Script ‘C:\view\mrichar2_apr\fixme\shared\shared-build.gradle’ line: 13

  • What went wrong: A problem occurred evaluating script. > Failed to apply plugin [id ‘org.samples.greeting’]

Plugin with id ‘org.samples.greeting’ not found.

  • Try: Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.

If I instead change the buildscript to be project.buildscript it complains that “classpath” has already been configured and cannot be changed.

Unfortunately, you can’t apply “buildscript” blocks from script plugins. You can externalize them in init scripts but not script plugins.
