Maven не работает под мятным

я бегу Windows 7 и Cygwin (последний)

Когда я использую базовую консоль Cygwin, Maven отлично работает

когда я открываю mintty и запускаю mvn, я получаю это исключение

$ mvn --version java.lang.NoClassDefFoundError: org/codehaus/plexus/classworlds/launcher/Launcher Caused by: java.lang.ClassNotFoundException: org.codehaus.plexus.classworlds.launcher.Launcher at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: org.codehaus.plexus.classworlds.launcher.Launcher. Program will exit. Exception in thread "main" 

я не вижу ничего другого. вот мои окружения

я обычно начинаю копать с java_home и classpath, но тот факт, что он работает в основной оболочке cygwin, просто убивает меня.
