The default source folder for a Java Maven project is <code>src/main/java</code>. In the project on the right, the source folder is set to <code>src</code> via the following line in the <code>pom.xml</code> file:

<pre><code>&lt;sourceDirectory&gt;src&lt;/sourceDirectory&gt;
</code></pre>

If you remove the line or change the value, right-click the project and choose Maven > Update Project... to have Eclipse read the <code>pom.xml</code> file and update the source folder location accordingly.

blocks|key|3454800|text|的区别：让我们先了解一下这两个文件夹的含义。在左边的图像中，src/main/java是eclipse用来构建项目的源文件夹。在右侧的图像中，src是包含main.java包的源文件夹|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3454801|解决方案：无法编辑源文件夹，因此您必须复制文件并创建一个名为src//java的新源文件夹。|3454802|entityMap^0|0|4|0|0|5|Y|C|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

Difference: Let's first understand the meaning of both the folders. In the left image src/main/java is the source folder which is used by eclipse to build the project. In the right image src is the source folder with the package main.java

Solution: It is not possible to edit your source folder So you have to copy your files and create a new source folder with name src/main/java.

I think i did right now. I clicked right, choosed "Build Path" -> "New Source Folder". Then it worked. With the Properties-Menue "Java Build Path" it didn't work.

Thanks - Enomine

blocks|key|434818|text|以src/main/java作为源文件夹的项目是maven项目。Maven是一个构建的基础设施。管理库依赖关系，并提供项目文件夹的约定，如单元测试源的src/test/java，以及图像和*.properties文件等非java源的src/main/resources。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|434819|最好是将项目导入为maven项目(这里不是gradle)。您可能需要eclipse中的一个插件；有一段时间我使用的是另一个IDE。|434820|创建一个新的maven作为试验。|434821|Maven项目是由pom.xml控制的，因此最好将其识别为maven项目。|434822|entityMap^0|1|D|23|D|38|I|O|5|0|0|0|9|7|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|D]]|E|@]|F|$]]|$1|G|3|H|5|6|7|X|8|@]|E|@]|F|$]]|$1|I|3|J|5|6|7|Y|8|@]|E|@]|F|$]]|$1|K|3|L|5|6|7|Z|8|@$9|10|A|11|B|C]]|E|@]|F|$]]|$1|M|3|-4|5|6|7|12|8|@]|E|@]|F|$]]]|N|$]]

The projects with <code>src/main/java</code> as source folder are maven projects. Maven is a build infrastructure which i.a. manages library dependencies, and provides conventions for the project folders, like <code>src/test/java</code> for unit test sources, and <code>src/main/resources</code> for non-java sources like images and *.properties files.

Best would be to import the project as maven project (here it is not gradle). It might be that you need a plugin in eclipse; for a while I am using an other IDE.

Create a new maven as trial.

Maven projects are controlled by a <code>pom.xml</code> so a recognition as maven project is best.

blocks|key|5566516|text|在我看来，有两种方法可以解决这个问题:+1.转到项目主构建路径->+configure+build+path+->+Java+build+path，然后在源代码选项卡中添加你的src/+->+/java文件夹2.在“项目资源管理器”附近有一个箭头，可以让你自定义工作空间。您可以尝试更改“项目演示”或“包演示”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5566517|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In my opinion, there are two ways how to solve it:
 1. go to project -> build path -> configure build path -> Java build path and then in source tab add your src/main/java folder
 2. There is also an arrow near the "Project explorer" which lets you customize your workspace. you can try to change "project presentation" or "package presentation"

sometimes i face project structures in Package Explorer that are at "src/main/java". But if i work for myself it is only "src". Howto take controll of that?

Difference between two projects in eclipse: left: one folder named "src/main/java" right: one folder named "src", one subfolder named "main.java"

有时，我在Package Explorer中遇到位于"src/main/java“的项目结构。但如果我为自己工作，它只是"src“。该如何控制呢？eclipse中两个项目的区别:左:一个文件夹名为"src/main/java“右:一个文件夹名为"src"，一个子文件夹名为"main.java”​​谢谢- Enomine
