the work around is to have to go into your .grails\2.0.3\projects\tempPlugin\resources directory (note this is not in your eclipse workspace)

then manually create an empty grails-app direcory

re run the run-war command it it works now

I have a similar problem running "mvn clean install" against a grails plugin project using grails 2.0.3 and maven 2.2.1. However, the suggested workaround does not fix it. What I'm actually trying to do here is install this grails plugin in the local maven repo. I'm not sure this is the right command to use, but "grails maven-install" is broken in this grails-maven project, so I thought the mvn install command might do the trick.

These are the steps I followed to create the plugin project that fails on "mvn install" per yesterday's post. One red flag is the artifactId of the plugin: when "envAuthThree" is specified as the artifactId on the archetype:generate command, 1) the plugin descriptor is generated incorrectly as "HThreeGrailsPlugin.groovy" (which I corrected) and 2) "mvn grails:validate-plugin" fails until the artifactId in the pom is changed from the auto-generated "envAuthThree" to "env-auth-three". Please let me know if there's a preferred series of steps to create a grails plugin project under maven.

1. create new grails-maven plugin project using maven's grails archetype
mvn archetype:generate -DarchetypeGroupId=org.grails -DarchetypeArtifactId=grails-maven-archetype -DarchetypeVersion=2.0.3 -DgroupId=com.iii -DartifactId=envAuthThree

  • in pom.xml
    • change packaging to "grails-plugin"
    • change maven-compiler-plugin from 1.5 to 1.6
    • change artifactId from envAuthThree to env-auth-three (otherwise mvn grails:validate-plugin fails)
  • run mvn initialize
    • plugin descriptor name is mangled by the initialize action
    • change name of plugin descriptor if required (s/b EnvAuthThreeGrailsPlugin.groovy)
  • modify EnvAuthThreeGrailsPlugin.groovy
    • customize for this project
    • omit spring-security-core dependsOn (add this in later)
  • ensure app name and version correspond:
    • pom.xml - change artifactId from envAuthThree to env-auth-three (per validate-plugin), 1.0-SNAPSHOT
    • application.properties - change envAuthThree to env-auth-three (per validate-plugin), 1.0-SNAPSHOT
    • EnvAuthThreeGrailsPlugin.groovy - 1.0-SNAPSHOT
  • modify BuildConfig.groovy
    • "pom true" (dependencies and plugins will be defined in pom.xml)
    • "useOrigin true" (don't cache dependencies during development)
    • no dependencies or plugins should be defined in BuildConfig

2. run maven-grails commands

  • mvn grails:init-plugin - success
  • mvn grails:validate-plugin - fails
    • The plugin name in the pom.xml [envAuthThree] is not the expected 'env-auth-three' or 'grails-env-auth-three'. Please correct the pom.xml or the plugin descriptor.
    • changing artifactId in pom.xml from envAuthThree to env-auth-three
    • run again - success
  • mvn grails:maven-clean - success
  • mvn grails:maven-compile - success
  • mvn grails:package-plugin - success
  • //grails maven-install - fails
  • // Script 'MavenInstall' not found
  • mvn install - fails
    • app.name [envAuthThree] in application.properties is different of the artifactId [env-auth-three] in the pom.xml
    • > change app.name in application.properties from envAuthThree to env-auth-three
    • mvn install - fails
      • FATAL ERROR - java.lang.OutOfMemoryError: PermGen space
      • > change $MAVEN_OPTS from -Xms512m -Xmx2048m to -Xms1024m -Xmx4096m
    • mvn install - fails
      • FATAL ERROR - org.codehaus.classworlds.NoSuchRealmException: plexus.core
      • > add to $MAVEN_OPTS -XX:MaxPermSize=1024m
    • mvn clean install - fails
      • BUILD ERROR - Unable to start Grails
      • Embedded error: java.lang.reflect.InvocationTargetException
      • PermGen space
      • > change $MAVEN_OPTS -XX:MaxPermSize=4096m
    • mvn clean install - fails
      • Unable to start Grails
      • Embedded error: java.lang.reflect.InvocationTargetException
      • C:\branches\envAuthThree\target\resources\grails-app does not exist.
      • see http://jira.grails.org/browse/GRAILS-9058
      • adding the grails-app dir at ~/.grails/2.0.3/projects/envAuthThree/resources does not fix this problem.

Once I am able to successfully install this empty plugin, I'll start adding dependencies, plugins and artifacts one at a time.
