As you've discovered, you can't have a source folder inside another source folder, so before you can create src/main/javayou have to tell Eclipse not to treat srcas a source folder. To do this, right click on the srcfolder and select build path -> remove from build path.
正如您所发现的，在另一个源文件夹中不能有源文件夹，因此在创建之前，src/main/java您必须告诉 Eclipse 不要将其src视为源文件夹。为此，请右键单击该src文件夹并选择构建路径 -> 从构建路径中删除。
Once you have done this srcwill appear in the folder tree in its normal place, so you can create the mainand javafolders under it, and move the existing src/comto src/main/java/com. Finally right-click the newly-created javafolder and select build path -> use as source folder.
完成后，这src将出现在文件夹树中的正常位置，因此您可以在其下创建main和java文件夹，并将现有文件夹移动src/com到src/main/java/com. 最后右键单击新创建的java文件夹并选择构建路径 -> 用作源文件夹。

Open Properties > Java Build Pathfor the project. Select the Sourcetab and use Add Foldersto add source folders.
Properties > Java Build Path为项目打开 。选择Source选项卡并用于Add Folders添加源文件夹。

Remove the actual source folder definition in the build path and add a new source folder an name it src/main/java
删除构建路径中的实际源文件夹定义并添加一个新的源文件夹并为其命名 src/main/java

I have solved this issue by below steps:
我已经通过以下步骤解决了这个问题：
Right click the Maven Project -> Build Path -> Configure Build Path In Order and Export tab, you can see the message like '2 build path entries are missing' Now select 'JRE System Library' and 'Maven Dependencies' checkbox Click OK
右键单击 Maven 项目 -> 构建路径 -> 按顺序配置构建路径和导出选项卡，您可以看到类似“缺少 2 个构建路径条目”的消息现在选择“JRE 系统库”和“Maven 依赖项”复选框单击确定

the problem will be solved by checking on 'JRE System Library' and 'Maven Dependencies' checkboxs Click OK. this is found in the project's 'build path option'
该问题将通过选中“JRE 系统库”和“Maven 依赖项”复选框来解决。单击“确定”。这可以在项目的“构建路径选项”中找到

If you don't find the Included Path just add the path it will resolve.
如果您没有找到包含路径，只需添加它将解析的路径。

If the package structure is setup as src.main.java.com.inventica, instead of com.inventica, that's usually because under project properties > Java build path > Source, the source folder is setup as “src” instead of “src/main/java”. There's no easy way to fix this, so remove “src” as a source folder and click ok. Now eclipse will show a folder hierarchy “src/main/java”. Browse to the “java” folder > right click > build path > use as source folder. After this you may have to fix the Eclipse .project and .classpath files to have it use Maven to manage dependencies, builds etc. Typically, you can copy this from a working project since there isn't anything project specific here assuming you're structured as a standard Maven project.
如果包结构设置为 src.main.java.com.inventica，而不是 com.inventica，那通常是因为在项目属性 > Java 构建路径 > 源下，源文件夹设置为“src”而不是“src/主/java”。没有简单的方法来解决这个问题，所以删除“src”作为源文件夹，然后单击“确定”。现在 eclipse 将显示一个文件夹层次结构“src/main/java”。浏览到“java”文件夹>右键单击>构建路径>用作源文件夹。在此之后，您可能必须修复 Eclipse .project 和 .classpath 文件，使其使用 Maven 来管理依赖项、构建等。通常，您可以从工作项目中复制它，因为这里没有任何特定于项目的假设您是构建为标准的 Maven 项目。

Simple solution would be create 'java' folder directly one the drive into src/main even before opening it in eclipse that way eclipse will not complain about the issue.
简单的解决方案是直接将“java”文件夹创建到 src/main 中，即使在 eclipse 中打开它之前，eclipse 也不会抱怨这个问题。
