Git推送到Heroku时checkstyle-suppressions.xml的正确存放位置

The error you're seeing makes it clear: the checkstyle plugin is looking for the suppression file at the root of your project under etc/config/checkstyle-suppressions.xml—not inside the target directory. The target folder is a build-generated directory that’s almost always excluded from Git (via .gitignore), so Heroku never sees files placed there during its build process. That’s why your previous attempt didn’t resolve the issue.

Here’s how to fix this properly:

• First, create the required directory structure at your project root:

  my_app/
  └── etc/
      └── config/
  

• Move your checkstyle-suppressions.xml file directly into my_app/etc/config/
• Commit this new directory and file to Git (critical, since Heroku only uses files tracked in your repo):

  git add etc/config/checkstyle-suppressions.xml
  git commit -m "Add checkstyle suppressions file at correct root path"
  

• Re-run your push command:

  git push heroku master
  

A quick sanity check: If your project’s checkstyle configuration (like in pom.xml or checkstyle.xml) specifies the suppression file path explicitly, confirm it matches the root-relative path we set up. For example, a line like <suppressions location="etc/config/checkstyle-suppressions.xml"/> will now resolve correctly from the project root.
