[JENKINS-45616] Multi-branch pipelines do not interpolate platform environment variables into Jenkins global environment variables

Did not test this on any previous versions of Jenkins/Plugins

Steps:

1. Install Maven and Gradle using SDKMAN (http://sdkman.io)


2. Install NodeJS using NVM (https://github.com/creationix/nvm)


3. Add a global environment variable PATH that appends the tool paths (${PATH}:${HOME}/.nvm/versions/node/v6.11.1/bin:${HOME}/.sdkman/candidates/maven/current/bin:...)


4. Create a multi-branch (Jenkinsfile) build that executes a shell command using sh

Result:

[Pipeline] sh

[***JOB***-TGZIHGC5MANL6BRDMLV3HGPUPVWZW5TYQK3AXDKNEHCXHUAIDQNQ] Running shell script

nohup: failed to run command ‘sh’: No such file or directory

[Pipeline] }

[Pipeline] // stage

[Pipeline] }

[Pipeline] // node

If I change the global environment variable to include /bin, /usr/bin etc. instead of using ${PATH} and dump out the value of ${PATH} during the build, I see the following:

[Pipeline] {

[Pipeline] sh

[***JOB***-TGZIHGC5MANL6BRDMLV3HGPUPVWZW5TYQK3AXDKNEHCXHUAIDQNQ] Running shell script

+ echo '${HOME}/.sdkman/candidates/maven/current/bin:${HOME}/.sdkman/candidates/gradle/current/bin:${HOME}/.nvm/versions/node/v6.11.1/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin'

${HOME}/.sdkman/candidates/maven/current/bin:${HOME}/.sdkman/candidates/gradle/current/bin:${HOME}/.nvm/versions/node/v6.11.1/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin

This suggests that the platform environment variables are not being interpolated into the Jenkins global environment variables.  Other Jenkins global environment variables do seem to be expanded however (such as if I set ${MAVEN_HOME} and use it in ${PATH}).

If I dump out ${PATH} from a non-pipeline Freestyle project shell step, I get the expected value (including both ${HOME} and ${PATH} expanded fully).
