dependencies {
classpath 'org.jenkins-ci.tools:gradle-jpi-plugin:0.10.2'
}
I get the following error when trying to run a unit test. Example code is below.
I was able to get past this error by including dependancy testCompile 'org.jvnet.hudson.main:hudson-core:1.159' but that then said other classes where missing. This doesn't see the correct path to go down anyway.

added a comment - I confirm that adding the matrix-project fixes the problem:

added a comment - That seems to have fixed it, although I ended up adding it as jenkinsTest 'org.jenkins-ci.plugins:matrix-project:1.4@jar'.
I'm now getting a huge amount of warnings in in the console output which I can only assume means something isn't quite right (although as this is my first plugin I've got nothing to compare against):

JUnit plugin was extracted from core in 1.577, so is not an explicit dependency of Matrix Project plugin, even though it's used by that.
java.lang.InstantiationException: java.lang.NoClassDefFoundError: org/jenkinsci/plugins/scriptsecurity/sandbox/whitelists/ProxyWhitelist
That's Script Security plugin, but I'm not sure how this gets involved. It only became a dependency of Matrix Project plugin in 1.2.1 and 1.4.1, and isn't in 1.4.

added a comment - I'm happy with adding the matrix project dependancy

added a comment - if you only need that plugin in tests, then probably
jenkinsTest 'org.jenkins-ci.plugins:matrix-project:1.4@jar'
is better than
jenkinsPlugins 'org.jenkins-ci.plugins:matrix-project:1.4@jar'
?

Which coreVersion did you set in the build file? Only core versions 1.420 or later are supported, so adding a dependency to an ancient core version is not helping.
As of Jenkins 1.561 the Matrix project has been moved to a plugin outside of Jenkins core, so you might need to add a dependency to that plugin.
