Intellij IDEA 将 junit 测试放在 jar 中

Question

How to tell Intellij IDEA not to include test classes in artifact? I'm working on a lot of projects so it's better if there's a solution like "ignore everything in project-dir/test directory", or even better "put in the jar only classes from project-dir/src .

Answer 1

How are you configuring the jar file in IntelliJ IDEA?

If I go to Project Structure (cmd + ; on Mac, ctrl + shift + s on Windows) and select "Artifacts", when I add a new artifact using "From modules with dependencies" it gives me the option of including tests or not:

If I add a new jar file using "Empty", then I can choose exactly what appears in the jar file:

Here I select "Module Output" and this should only add the class files from your module, not the test files (assuming you have your test directory marked as a test directory, and not as a source directory).

If you look to the left of that screenshot, behind the project structure window, you can see that I have production code in src/main/java and test code in src/test/java, and this test code is coloured green - this does not appear in my jar file if I configure it this way.

Answer 2

You should take a look at Gradle. Gradle will provide you with jar tasks that will exclude test files, or those that you ignore. Gradle will only package files in the main directory.

src/main/java

src/test/java

I'm assuming you are not using a build system, and have all files in the root folder. Without direction the IDE will not know which files are tests files and include them in the jar.

You need a build system like Ant, Maven or Gradle. I recommend Gradle it will build as an IntelliJ project, and there are many plugins for the IDE.

Right click on project-dir/test Mark Directory as ->Test Source root Right click on all directory inside project-dir/test and Mark Directory as ->excluded

Now build Artifact it will remove test case

Also check in ctrl+alt+shift+s (file-> project structure ) Click on Artifact From left panel-> now on right side screen From output layout remove all junit or test case related jar
