Didn't work, command wasn't recognised. Have I done something wrong?

Hi 👋 Did you add the directory to the Path? https://gradle.org/install/#configure

Also consider whether you actually need an installation? In almost all cases a local installation is not needed and practically never used anyway. All builds should contain the 4 Gradle Wrapper files (or imho have a build bug) that define which Gradle version to use for that project and care about auto-provisioning and using that version. These files should always be used to execute a build. And please do not split topics across several threads. This makes following the conversation in the threads view very hard as the context of the other messages is missing. If you have additional information either edit the original message or post to its thread.
