Running install.jar crreated from izpack gives me no such method exception

Question

Built an install.jar using Izpack 5.0.0-beta10 and compiler.bat

When I try and run it using java -jar install.jar I get

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: com.izforge.izpack.util.file.FileUtils.close(Ljava/io/Closeable;)V

This on Windows I have JAVA_HOME set to Java 7 jdk, and typing java -version from the command prompt also gives me Java 7

I can build and run the same install.xml with Izpack 4.3.5 no problem.

Answer 1

You might be depending on a different version of izpack-util to that of the installer.

In any case, you're running an old version of 5.0. I'd suggest downloading the latest snapshot from the repository
