无法运行Grails项目GGTS(Could not run Grails project GGTS

我有一个在命令行中运行一个完美Grails项目。 当我尝试用它运行在GGTS

grails run-app

它第一次运行时没有任何错误。 于是，我停止了服务器，并使用Grails运行应用程序再次运行它。 现在出现以下错误。

我也试着删除.grails / 2.2.1 /项目/ MyProject的目录和更新的依赖关系。 刷新依赖工作正常，但运行的应用程序不GGTS工作。 我该怎么办？

Answer 1:

像往常一样，尝试按以下顺序如下

grails clean
grails refresh-dependencies
grails run-app

如果仍然无法正常工作，您可能需要删除您.grails / 2.2.2 /项目/ *，并重复上述步骤。

Answer 2:

事实证明，这个问题是由Java 7的版本引起的。 不要用户更新21那么错误就会消失。
