Eclipse Buildship Plugin:嵌套源文件夹

Question

我正在使用Gradle Buildship插件来构建我的Eclipse项目。

Gradle本身已经配置好了。因此，我可以从shell构建任何东西。

gradle项目有一个根文件夹和其他子项目。

当我点击Gradle -> Refresh Project时它告诉我:

Synchronize Gradle builds with workspace failed due to an unexpected error.
Cannot nest 'living_webapi/src/main/java/com/living/persistence/entities' inside 'living_webapi/src/main/java'. To enable the nesting exclude 'com/' from 'living_webapi/src/main/java'

Answer 1

唯一对我有效的是取消勾选"允许为源文件夹输出文件夹"选项。

步骤:

右键单击项目->属性
1. 单击属性弹出窗口左侧的Java Build Path
2. 点击Source选项卡
3. 取消选中"允许输出文件夹为源文件夹"复选框
4. 点击应用并关闭
5. 右键单击project -> Gradle -> Refresh Gradle project

Answer 2

我也遇到过这个问题。我的解决方案是设置项目属性。

在Java build Path -> Source中，将输出文件夹设置为default。有关更多细节，请参阅下图。
