It seems ant-launcher.jar is missing from the classpath, which is a separate dependency from main ant.jar.

I'm wondering because I don't know what jar I have to import.
Could somebody help me?
I think you need hadoop-commmon for this class.
http://mvnrepository.com/artifact/org.apache.hadoop/hadoop-common/2.7.2
Using the following code I get a NoClassDefFoundError caused by ClassNotFoundException:
File file = new File( "C:\\prototype.core.bl.xmodelval.xmodel-1.0.0.jar" );
URL url = file.toURI().toURL();
URL[] urls = new URL[] { url };
ClassLoader cl = new URLClassLoader( urls );
Class cls = cl.loadClass("de.zeb.control.prototype.core.bl.xmodelval.xmodel.entity.EntityNameLengthXModelValidationRule" );
The jar and the class in the jar are definitely available. The following exception is thrown by cl.loadClass. The full exception stack trace follows:

It seems strange for me that the full class name of the ClassNotFoundException doesn't match the name of the cl.loadClass.
Thank you for your help.
You might need to provide parent classloader, because otherwise the classloader you define won't be able to access any classes already present in your application. E.g.:
ClassLoader cl = new URLClassLoader( urls , getClass().getClassLoader());
