POGrails in Eclipse
text
Body
copied!<p>I'm trying to follow some of the introduction to Grails tutorials and am at the point where I want to try to see if I can use a debugger in Eclipse with my Grails applications. My grails application runs fine when I use the command to execute, but when I tried to use the Eclipse run configuration, I get the following error:</p> <pre><code>Exception in thread "main" java.lang.NullPointerException at java.io.File.<init>(File.java:194) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at org.codehaus.groovy.reflection.CachedConstructor.invoke(CachedConstructor.java:77) at org.codehaus.groovy.runtime.callsite.ConstructorSite$ConstructorSiteNoUnwrapNoCoerce.callConstructor(ConstructorSite.java:107) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCallConstructor(CallSiteArray.java:52) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callConstructor(AbstractCallSite.java:192) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callConstructor(AbstractCallSite.java:200) at grails.util.GrailsMain.run(GrailsMain.groovy:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:86) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:234) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1062) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:893) at org.codehaus.groovy.runtime.InvokerHelper.invokePogoMethod(InvokerHelper.java:744) at org.codehaus.groovy.runtime.InvokerHelper.invokeMethod(InvokerHelper.java:727) at org.codehaus.groovy.runtime.InvokerHelper.runScript(InvokerHelper.java:383) at org.codehaus.groovy.runtime.InvokerHelper$runScript.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:40) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:117) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:129) at grails.util.GrailsMain.main(GrailsMain.groovy) </code></pre> <p>I figure it's a configuration issue (I did recently set the GRAILS_HOME environment variable and that seems to be correct) but that error message doesn't really give me much to go. </p> <p>Suggestions?</p>
