Eclipse不会编译成bin，无法找到或加载主类

Question

I've been using eclipse to program in java for a month or two now. I have a package boats, within it many classes all run from the main class boatGame. Eclipse has built and rebuilt the numerous iterations of my program until today, when it seems to have stopped cooperating. When I hit run, I get the error,

Error: Could not find or load main class boats.BoatGame

When I investigated, I found that the Bin folder is empty and devoid of the replicated source file components as .class files. An unrelated program would run from eclipse, but when I deleted it's bin file components, it too gave me the same error, with its bin folder also remaining completely empty.

My default output folder is boats/bin, and a search of my computer didn't yield any .class files that may have been built in the wrong place. I have also deleted and re-installed both eclipse and JDK. Does anyone have any pointers as to how I could start building programs within eclipse again?

Answer 1

我在项目名称上运行了重构/重命名，然后将其重命名为原始版本并修复了问题。

Answer 2

This problem occurs with me too. Here is the solution:

1. Open the folder in which the .java files are present of the project boats (boats/src).

2. Now, go to eclipse and make a new project. (boatsA or boatsB, whatever you like).

3. Make the same(name) classes as in boat (it may take time).

4. Copy the text in each .java file and paste it in respective classes.

5. Save all classes.

6. Run it!

I am 100% sure that it will run.

Though in your case, it may work.
