将GitHub存储库克隆到IntelliJ IDEA Java类中

Question

I work from two different laptops and naturally use GitHub VCS to link the my work among the machines. I recently started a Java project where the .class files are saved in the src/ directory.

Whenever I clone the remote repo into my 2nd machine none of the classes will run. I have the proper SDK/JDK assigned and setup.

here is the error message:

Process finished with exit code 1

I suspect the .iml files is to blame? or is it also because I am using .gitignore?

Whenever I create a new IDEA project and merely copy the code into a new java class file the code executes without flaws.

Answer 1

As a rule of thumb I don't check in IDE settings because they may vary between machines (like JDKs may be in different locations, IDE-specific executables may be at different paths etc.). This is the IntelliJ/sbt-related excerpt of my .gitignore:

target/
.project
.idea*
/project.plugins/project
ca.log
*.iml

So add that to your .gitignore, set up the project on both machines and see if it works.
