IntelliJ构建的JAR包无法包含InvalidArgumentException问题求助

Hey Aaron, let's break down why you might be hitting issues with InvalidArgumentException even though your JAR builds and runs otherwise. Here are common culprits and actionable steps to debug:

• Modular Project Configuration Gaps
  If your project uses Java modules (has a module-info.java), double-check that your module properly accesses the java.base module (where InvalidArgumentException resides). While java.base is implicitly required for most projects, misconfigurations like restricted exports or accidental module restrictions could cause runtime access issues.

• Incomplete Artefact Packaging
  Head back to your Artefact Structure settings in IntelliJ. Verify that the class file containing the code that throws InvalidArgumentException is actually included in the JAR output. You can manually unzip your built JAR and check if the corresponding .class file exists in the correct directory structure. If it's missing, adjust your artefact to include the relevant module or source set.

• JDK Version Mismatch Between Build and Runtime
  Even though InvalidArgumentException has existed since JDK 1.5, a mismatch between the JDK you used to build the JAR and the one you're using to run it could cause unexpected behavior—especially if you're using modular features. Run java -version to confirm the runtime JDK, and compare it to the Project SDK set in IntelliJ's Project Structure.

• Subtle Code Logic Issues
  Sometimes the problem isn't with the exception itself, but how it's being thrown or handled. For example:

  // Check if the value triggering the exception has unexpected edge cases
  if (input < 0) {
      throw new IllegalArgumentException("Input cannot be negative: " + input);
  }
  

  Verify if the value you're passing when throwing the exception is causing unintended side effects, or if the exception is being swallowed incorrectly elsewhere in your code.

• IntelliJ Cache Corruption
  IDE caches can sometimes lead to mismatched builds. Try these steps to rule that out:

  1. Go to File > Invalidate Caches... and select "Invalidate and Restart"
  2. Rebuild your entire project with Build > Rebuild Project
  3. Delete and re-create your artefact in File > Project Structure > Artefacts before rebuilding the JAR

To narrow this down further, it would help to share:

• The full stack trace of the exception you're seeing (this will pinpoint exactly where and why it's failing)
• The code snippet where you're throwing InvalidArgumentException
• If it's a modular project, the content of your module-info.java
• The exact command you're using to run the JAR
