I have what looks to be exactly the same problem lamented here: Grails 2.3.0 Not Running
However none of the tenetative solutions had any effect.
When I attempt to run
grails clean --stacktrace
I get:
| Environment set to development.
| Error Error executing script Clean: _GrailsClasspath_groovy$_run_closure1 (NOT
E: Stack trace has been filtered. Use --verbose to see entire trace.)

Per the link that I refer to I tried:
- deleting my application's target directory
- deleting my home directory's .grails/.slcache
- deleting my workspace's .metadata.plugins\org.grails.ide.eclipse.core\2.3.1.slcache
Before trying any of those I wiped my grails_home directory and replaced with a redownloaded copy of grails 2.3.1
Reverting Grails 2.1.5 also did not help
Nothing in the stack trace points to anything that I explicitly authored so I'm at a loss for what I might have done wrong.
I'm using/running:
- 64 bit java version 1.7.0_45
- Groovy 2.1.9
- Windows 7 Enterprise SP1, 64-bit OS
I have an arbitrary grails app that I created to refer to the BuidConfig that it refers to since I'm attempting to upgrade from Grails 2.1.5 and that runs
The full stack trace is:
| Loading Grails 2.3.1
| Configuring classpath
| Configuring classpath.
| Environment set to development

回答1:
The grails.project.work.dir - which by default would be something like ~/.grails/projects/${appName} had a directory named: "scriptCache"
Emptying the scriptCache contents enabled me to move forward.
