eclipse中的java源文件夹

Question

我已经在Eclipse中将hadoop源代码作为Java项目导入，在Eclipse中，包名被视为文件夹。但当我尝试运行它时，它抛出“找不到主类”。如何更改结构或如何运行它

Answer 1

你跟踪the instructions in the BUILDING.txt file了吗

Importing projects to eclipse
When you import the project to eclipse, install hadoop-maven-plugins at first.

  $ cd hadoop-maven-plugins
  $ mvn install

Then, generate eclipse project files.

  $ mvn eclipse:eclipse -DskipTests

At last, import to eclipse by specifying the root directory of the project via
[File] > [Import] > [Existing Projects into Workspace].
