I updated my 2.2.3 project to the 2.3M2. As soon as you make a clean and refresh of the dependencies, with the un-checked options every command from GGTS leads to the grails prompt presented. But the prompt can't be used to enter the commands, because this leads to error, that the build listener can't be load. This also happens with a newly created 2.3 project. Setting this setting back resolves the issue, but leads to many unneeded started Grails consoles . I even tested it with the latest nightly of IDE, Grails and Groovy, but all remains the same.
