Add maven capability to Team Services build agent

Question

What's the correct way to setup maven on a Team Services Default build agent?

What I have done so far:

• I have downloaded the agent on a virtual machine
• I have manually installed java and maven on that machine (C:\Java\jdk1.8.0_101 resp C:\Java\maven\apache-maven-3.3.9)
• I have added a few environment variables (maven, MAVEN_HOME, M2_HOME)
• after that I install the agent using the powershel script .\config.cmd

The agent gets succesfully registered in my visualstudio.com environment, but the maven capability does not get picked up:

After reading several other posts, I manually added the "maven" capability to the agent:

After all this I can start a build that requires maven. But unfortunately the build fails:

How do I get maven to work properly on my default build agent? I cannot find a solution in the MS documentation.

To answer my own question. The mistake that I made was that I created the environment variables as user variables instead of system variables. To sum things up, here's what's needed:

• download the agent on a virtual machine
• installed java and maven on that machine
• add SYSTEM environment variables M2_HOME and JAVA_HOME
• install the agent using the powershel script .\config.cmd
