Bug 828650 – dev-util/jenkins-bin: jenkins.service unit using system java

• Status: UNCONFIRMED
• Product: Gentoo Linux

As a suggestion, would be better to avoid defining in jenkins.service the ExecStart with /usr/bin/java, but instead use only java, so it can be override by PATH definition to use another java version if required. I just define a drop-in like the following, but doesn't work because is not possible to override ExecStart:

[Service]
Environment=JAVA_HOME=/usr/lib64/openjdk-11
Environment=JDK_HOME=/usr/lib64/openjdk-11
Environment=PATH=${JAVA_HOME}/bin/:${PATH}
ExecStart=java ${JENKINS_JAVA_OPTIONS} ...

Jenkins service only starts when systemd service type is "simple".

I saw this approach to define jenkins.service where is possible to define the required environment variables to set the preferred java version to use with jenkins:
