A user has asked me to support running my plugin on a slave but whatever I
try I keep getting an “Unable to serialize” exception. My code is now
about as basic as it gets and still failing. Any ideas?
I’m running Jenkins 2.19.1 and my plugin has a Jenkins version dependency
of '1.642.3'.
@Override
public boolean perform(final AbstractBuild<?, ?> build, final Launcher
launcher, final BuildListener listener) throws IOException,
InterruptedException {
return launcher.getChannel().call(new MasterToSlaveCallable<Boolean,
IOException>() {
private static final long serialVersionUID =
-8921104780200640023L;
@Override
public Boolean call() throws IOException {
return true;
}
});
}
