[jenkins-tfs-plugin] Unable to build

[Mike M.]

I am setting up a TFS 2010 project with the latest version of Jenkins
v1.428 and the tfs-plugin v1.19 and I am getting a strange error
message. I am not sure where this error originates from but some help
would be much appreciated.

The plugin is compiled using Java 6, and you are using Java 5, as the
String.isEmpty() method was first added in 6 (!?). The quickest fix is
to update your Java version, or wait until I release a new version
that is Java 5 compatible. I just need to figure out how I can make
sure that the code is 5 compatible in my build process.

You can check for compatibility with animal-sniffer

Thanks for the tip for the animal-sniffer.

Ive fixed the problem, and released a new version containing it (1.20).

Great, this resolved my issue with TFS.  Java 6 works!  thanks
