IDEA Error:java: Compilation failed: internal java compiler error

created at 08-30-2022 views: 8

There are two possible cases where Error:java: Compilation failed: internal java compiler error occurs.

1. May be the jdk version is inconsistent

Check the following three points respectively to see if they are consistent.

  • The version in Preferences -> Compiler -> Java compiler sets the SDK version
  • SDK version in File -> Project Structure -> Project
  • File -> Project Structure -> Module -> Module SDK version in each module Dependencies

2. The memory setting of the compilation environment may be insufficient.

Preferences -> Compiler -> Shared build process heap size

Increase the default 700M memory.
