From within a gradle build I need to kickoff a gradle build of another
project. The projects are not really subprojects and don't share any
directory structure. I will know via a system property where the
second project is and I know ahead of time the name of the target that
I need to execute in the second project. Both projects are setup to
be built with the gradle wrapper.
How can I configure "project a" to initiate a build of "project b" for
a scenario like that?
In the Gradle 0.9 release, there will be a GradleBuild task you can use
to execute a build. This task is available in recent 0.9 snapshots. Some
examples at
http://gradle.org/latest/docs/userguide/organizing_build_logic.html#sec:external_build
In Gradle 0.8, you can use the GradleLauncher API to execute a build
(this is what the GradleBuild task uses). For example:
task otherBuild << {
// use a copy of our existing build
def startParams = gradle.startParameter.newBuild()
// configure the project dir and which tasks to execute
startParams.currentDir = otherProjectDir
startParams.taskNames = ['someTask']
// run the build
GradleLauncher.newInstance(startParams).run().rethrowFailure()
}
Have a look at
http://gradle.org/0.8/docs/javadoc/org/gradle/GradleLauncher.html and
http://gradle.org/0.8/docs/javadoc/org/gradle/StartParameter.html for
more details.
