First install the plugin JarEditor from marketplace, IDEA at least version 2020.3

External jars: File->Project Structure->Libraries->Add Library , then you can see the decompiled jar.
After modification, click Save(Compile) to compile and save the currently modified java content.
Finally click Build Jar to write the compiled and saved class file into the Jar package.
Modifying the resource files in the jar package is also supported.
In the project view of the jar package, right-click to see JarEditor->New/Delete and other operations, where you can add/delete/rename/copy/paste files.
- The JDK that the compilation depends on is the JDK of your SDK list. You can choose SDK and target version of the compiled class.
- The classpath you depend on when compiling java is the dependency of the project. If the dependency package cannot be found, you can add the dependency.
- Save(Compile) will save the modified files to the subdirectory jar_edit_out of the directory where the jar package is located. Build Jar will incrementally write the modified files to jar, and finally delete this directory.
When compiling and selecting SDK Default, the corresponding JDK version is as follows
