Hi, I'm trying to upgrade the gwt-maven plugin to support 1.6 release. I've applied the shell / compiler changes and now try to launch the compiler. I got a strange error :
[INFO] Compiling 15 permutations [INFO] Process output [INFO] [ERROR] java.lang.NoClassDefFoundError: com/google/gwt/ dev/CompilePermsServer [INFO] [ERROR] Caused by: java.lang.ClassNotFoundException: com.google.gwt.dev.CompilePermsServer [INFO] [ERROR] at java.net.URLClassLoader$1.run (URLClassLoader.java:200) [INFO] [ERROR] at java.security.AccessController.doPrivileged (Native Method) [INFO] [ERROR] at java.net.URLClassLoader.findClass (URLClassLoader.java:188) [INFO] [ERROR] at java.lang.ClassLoader.loadClass (ClassLoader.java:307) [INFO] [ERROR] at sun.misc.Launcher$AppClassLoader.loadClass (Launcher.java:301) [INFO] [ERROR] at java.lang.ClassLoader.loadClass (ClassLoader.java:252) [INFO] [ERROR] at java.lang.ClassLoader.loadClassInternal (ClassLoader.java:320) [INFO] [ERROR] Could not find the main class: com.google.gwt.dev.CompilePermsServer. Program will exit. [INFO] [ERROR] Exception in thread "main" The plugin creates a native command script, like this one : "D:\jdk6\jre\bin\java" -Xmx512M -cp "D:\repository\org\codehaus\mojo \gwt-maven-plugin\1.1-SNAPSHOT\gwt-maven-plugin-1.1-SNAPSHOT.jar" org.codehaus.mojo.gwt.fork.ForkBooter "D:\projets\webapp\target \gwt.classpath" com.google.gwt.dev.Compiler -gen "D:\projets\webapp \target\gen" -logLevel INFO -style OBF -war "D:\projets\webapp\target \webapp-1.0.0-SNAPSHOT" -localWorkers 2 com.sfr.bios.rc.CADM The "ForkBooter" class is used to bypass Windows command line length limitation. It created a child classloader based on project dependencies list. In my case, the gwt.classpath file looks like : D:\projets\webapp\src\main\java D:\projets\webapp\target\generated-sources\gwt D:\projets\webapp\src\main\resources D:\projets\webapp\target\classes D:\repository\com\google\gwt\gwt-user\1.6.0\gwt-user-1.6.0.jar D:\repository\com\google\gwt\gwt-dev\1.6.0\gwt-dev-1.6.0-windows.jar D:\repository\com\google\gwt\gwt-servlet\1.6.0\gwt-servlet-1.6.0.jar ... As you can notice, the expected gwt-dev jar is present. I suppose the "Compiling * permutations - Process output" step has some Classloader issue that doesn't support our nested ClassLoader. Maybe it uses SystemClassloader directly ? I didn't get further with this issue debugging the compiler to understand what's wrong, maybe you've got an idea ?
