Eclipse cannot load resources directory (Build Path Problem)
提问by user496949
I found there is an exclamation mark in the icon of my project. I guess it is caused by the resources directory is not loaded.
我发现我的项目图标中有一个感叹号。估计是资源目录没有加载造成的。
Here is part of my .classpath file, anything can be wrong?
这是我的 .classpath 文件的一部分，有什么问题吗？
<classpathentry kind="src" path="src/test/java" output="target/test-classes" including="**/*.java"/>
<classpathentry kind="src" path="src/main/java" including="**/*.java"/>
<classpathentry kind="src" path="src/main/resources" excluding="**/*.java"/>

Just adding this here if someone stumbles on the same question: The problem was solved by refreshing the project (Selecting the project root and hitting F5), see comments.
如果有人偶然发现同一个问题，只需在此处添加：通过刷新项目（选择项目根目录并按 F5）解决了问题，请参阅评论。
Eclipse does not refresh the workspace projects by default when starting up. You can add an start-up option (the flag is -refresh, see herefor details) for performing a global refresh of the workspace on startup. This will reconcile any changes that were made in the file system since the platform was last run.
默认情况下，Eclipse 在启动时不会刷新工作区项目。您可以添加启动选项（标志是-refresh，请参阅此处了解详细信息）以在启动时执行工作区的全局刷新。这将协调自平台上次运行以来在文件系统中所做的任何更改。
Removing and re-adding the source folder to project Build path can be done like this:
将源文件夹删除并重新添加到项目构建路径可以这样完成：
- Right click on the source folder, select Build path -> Remove from build path
- Select the folder from the "normal" (non-source folder) -directory tree (usually shows way down in your project tree), right click the desired directory and select Build path -> Use as Source folder
- 右键单击源文件夹，选择构建路径 -> 从构建路径中删除
- 从“普通”（非源文件夹）-目录树（通常在项目树中向下显示）中选择文件夹，右键单击所需目录并选择构建路径 -> 用作源文件夹

Refreshing the project, which is what the accepted answer suggests, failed for me.
刷新项目，这是公认的答案所暗示的，对我来说失败了。
Here is what I did to resolve this issue:
这是我为解决此问题所做的工作：
- Right click , and then select
Build Path -> Configure Build Path... -> Order and Export - Look for the src/main/resources folder in the entries list. Mine was called
<my project folder>/src/main/resources. - Move
<my project folder>/src/main/resourcesto the bottom of the dependency list by selecting it and clicking the button titledBottom.
- 右键单击 ，然后选择
Build Path -> Configure Build Path... -> Order and Export - 在条目列表中查找 src/main/resources 文件夹。我的被称为
<my project folder>/src/main/resources。 <my project folder>/src/main/resources通过选择依赖项列表并单击标题为 的按钮移动到依赖项列表的底部Bottom。
This resolved the issue for me. In my case, the resourcesentry was above the src/main/javaand src/main/testentries, which seems to have been causing problems.
这为我解决了这个问题。就我而言，resources条目位于src/main/java和src/main/test条目之上，这似乎引起了问题。
