Grails插件安装错误：java.lang.NoClassDefFoundError:org/Grails/plugins/tomcat/fork/ForkedTomcatServer$\u findSystemClasspathJars\u closure3

在安装插件后，我遇到了这个错误，（我试图安装2个插件，但发生了相同的错误）我正在尝试安装Grails AWS插件
但以下是Buildconfig.groovy和错误：

在没有分叉的情况下运行应用程序修复了该问题

只需将这一行添加到BuildConfig.groovy

grails.project.fork.run=false

我在受影响的回购中运行了

rm-Rf./target

，然后重建了你尝试过清理你的应用程序吗？是的，我尝试过，但没有成功。但是当我手动将插件解压到plugins文件夹并手动安装时，它就工作了。
