I followed the instructions in the plugin tutorial to create a new plugin, and I can't seem to use java 8 this way:

https://wiki.jenkins-ci.org/display/JENKINS/Plugin+tutorial

$ mvn -U org.jenkins-ci.tools:maven-hpi-plugin:create

$ # open up pom.xml, change 'java.version' to 8

$ mvn package

I get the following error:

```

[INFO] --- animal-sniffer-maven-plugin:1.14:check (check) @ wtf ---

```

Is this a known issue? Any suggested work-around?

You probably have to override the animal sniffer config with the correct signature file version.

There is none for Java 8 yet AFAICT, so until there is, 8+ plugins are
not supported by this POM I guess, unless you can configure out how to
suppress the Animal Sniffer execution.

My apologies; looked for it in my Maven repository index and it did
not show up there for some reason.

Anyway, https://github.com/jenkinsci/plugin-pom/pull/21 should fix it for you.
