Configure custom build environments
By default, builds will run using the latest supported versions of our main tools - Ruby, PHP, Java and Node. However, if you have a project that requires a specific version of one of those tools, you can create your own custom build environment.
Head to Build configuration within your project's Build Pipeline, then update any of the main tools at the top of the screen, to use one of the versions provided.
Once you've done so, future builds in that project will always use those versions of the tools.
