在 Eclipse 中创建类时未列出的包

Question

I am facing a couple of issues in Eclipse and I feel they are related.

1. I cannot see the structure of packages in style package.subpackage1.subpackage2 but in the folder structure we see in windows explorer ie
   package
   |--- subpackage1
   |---subpackage2

2. While I try to create a class in a package , it is added to a default package and I cannot see a package as the packages are not listed.

An illustration of the problem

I checked perspectives as well - the issue persists in Java or JavaEE perspectives. I also changed the "Package Presentation" to "Hierarchical" but it wouldn't help. I checked with Package Explorer as well as Project Explorer. I am using Photon Release (4.8.0).

I tried searching it on Google and here in StackOverflow too but found nothing relevant thus seeking help from the community.

Answer 1

您将 Java 类文件放入源文件夹src/main/ （在 Maven 中默认情况下.java文件将被忽略以进行编译）而不是放入源文件夹src/main/ 。

Answer 2

Problems seem to be that you do not have a source folder. Right-click on your project -> Build Path -> Configure Build Path

In Configure Build Path select Source tab. Add source folder src/main/java. Create your packages and java files in this folder
