I need assistance to add a wrapper to an old gradle (v2.12) project, but I'm unable to run the wrapper tasks due to the following error:

Failed to apply plugin [class 'fi.jasoft.plugin.GradleVaadinPlugin']

Your gradle version (4.2.1) is too old. Plugin requires Gradle 2.0+

According to the error, I need to upgrade my gradle version, yet I have version 4.2.1 installed locally. Is there anyway to run the wrapper task with a specific version?

Gradle 4.2.1

Thanks to the link and answer from @Opal, I solved the issue by

  1. Installing SDKMAN
  2. Downgrading my local gradle version to 2.12: sdk install gradle 2.12
  3. Run the wrapper command
  4. Restore my local version to 4.2.1: sdk install gradle 4.2.1
