Question

我已导入Grails项目，并尝试将其转换为Grails＆＃34;。当我这样做时，我在apache commons日志包中获得NoClassDefFound。我在哪里添加罐子？这是在IDE的类路径，Grails类路径还是应用程序的类路径中？它似乎没有在grails-2.2.4 / lib中。这是我期待的第一个地方。这似乎使用常春藤，所以它应该作为依赖吗？以下是我看到的错误：

删除jdk1.8。我安装了1.7和1.8 jdks，1.8是osx的默认运行时。该项目被指定为1.7，但GGTS正在查看默认的Java运行时。删除1.8后，一切都按预期工作。

使用NoClassDefFoundError GGTS转换为Grails失败
