I am working on a grails app and need to remove Tomcat plugin in order to be able to host on Google App Engine (Also to use Jetty for another project)

As instructed on Grails app engine documentation, I need to remove Tomcat as GAE apps only runs on their server.

However, I keep on getting this error (The error message is much longer, only post the first few lines): 

: Unable to delete file C:\Users\Rama\.grails\1.3.7\projects\ccubemanager\plugins\tomcat-1.3.7\lib\catalina-ant.jar
at org.apache.tools.ant.taskdefs.Delete.handle(Delete.java:624)
at org.apache.tools.ant.taskdefs.Delete.removeDir(Delete.java:683)

at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288)
at sun.reflect.GeneratedMethodAccessor47.invoke(Unknown Source)

I am wondering if deleting the catalina-ant.jar manually would be a wise choice.

I tried to manually delete the whole /plugin directory anyway following this and it caused more mess that I cannot run any command on the app:

groovy.lang.MissingMethodException: No signature of method: java.math.BigInteger.call() is applicable for argument types: (java.lang.String) values: [target/classes]

I also try to start an entirely new project and uninstall tomcat, surprisingly it does not work either?

I am using Grails 1.3.7; STS 2.6.0; Windows 7

Could anyone please help, thanks alot!!

  • I believe there are some issues with OpenJDK and the latest Grails that prevent it working on the App Engine... http://stackoverflow.com/questions/4978879/grails-vs-gaelyk-for-new-groovy-appengine-application/4979085#4979085 – tim_yates Apr 07 '11 at 13:37

You should be able to uninstall tomcat by running the following command from the root of the project grails uninstall-plugin tomcat.

This will fail if another process has locked any of the files that the command needs to delete - this could be what is preventing catalina-ant.jar from being deleted. There are various tools available for windows that will tell you which process has a lock on a file. I've used unlocker in the past.
