报错内容

Error running ‘HelloWorld’: Command line is too long. Shorten command line for HelloWorld or also for Application default configuration.

解决方法

修改项目下 .idea\workspace.xml，找到标签

<component name="PropertiesComponent">

在标签里加一行

<property name="dynamic.classpath" value="true" />

如下图所示：

<component name="PropertiesComponent">
  <property name="RunOnceActivity.OpenProjectViewOnStart" value="true" />
  <property name="last_opened_file_path" value="$PROJECT_DIR$/src/test/java/com/XXX/util" />
  <property name="project.structure.last.edited" value="Global Libraries" />
  <property name="project.structure.proportion" value="0.0" />
  <property name="project.structure.side.proportion" value="0.2" />
  <property name="dynamic.classpath" value="true" />
</component>

也有可能是以下样式：

<component name="PropertiesComponent"><![CDATA[{
  "keyToString": {
    "RunOnceActivity.OpenProjectViewOnStart": "true",
    "RunOnceActivity.ShowReadmeOnStart": "true",
    "settings.editor.selected.configurable": "preferences.pluginManager"
  }
}]]></component>

添加以下内容即可：

"dynamic.classpath": "true"

最终展示效果为：

<component name="PropertiesComponent"><![CDATA[{
  "keyToString": {
    "RunOnceActivity.OpenProjectViewOnStart": "true",
    "RunOnceActivity.ShowReadmeOnStart": "true",
    "settings.editor.selected.configurable": "preferences.pluginManager",
    "dynamic.classpath": "true"
  }
}]]></component>
