Eclipse Buildship插件:嵌套源文件夹

Question

我使用Gradle Buildship插件来构建我的Eclipse项目。

Gradle本身配置良好。所以，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

唯一对我起作用的是取消勾选“允许源文件夹的输出文件夹”选项。

步骤：

1. 右击属性弹出窗口左侧的项目和Properties
2. Click on Java Build Path
3. 单击源代码选项卡
4. 取消选中"Allow output folders

source folders“复选框

1. 单击Apply -> Close
2. 右键单击项目-> Gradle ->刷新Gradle项目

Answer 2

我也有这个问题。我的解决方案是设置项目属性。

在Java build Path -> Source中，将output folder设置为default。有关更多详细信息，请参见下图。

Project Properties -> Java build path -> Source
