Injecting environment variables into Jenkins build process with shell script

initial situation

I have a Jenkins build project where I do pretty much everything by calling my build script ( ./jenkins.sh

). I am building a Cordova project that depends on specific versions of Node and Xcode. I am running builds on Macs with the latest macOS Sierra.

While I am setting environment variables in Jenkins build using EnvInject Plugin ( https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin ):

purpose

I want the environment variables to be set using the build script as well, not in Jenkins Build. This way the environment variables are also under version control and I don't need to touch Jenkins Build itself.

Basically I need to rebuild the EnvInject Plugin logic using bash.

What I tried # 1

In my jenkins.sh

build script, I have set environment variables withexport

jenkins.sh:

#!/bin/bash -ve

nodeVersion=7.7.8
xcodeVersion=8.3.1
androidSDKVersion=21.1.2

export DEVELOPER_DIR=/Applications/Xcode_${xcodeVersion}.app/Contents/Developer
export ANDROID_HOME=/Applications/adt/sdk
export PATH=/usr/local/Cellar/node/${nodeVersion}/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/usr/local/bin:/Applications/adt/sdk/tools:/usr/local/bin/:/Applications/adt/sdk/build-tools/${androidSDKVersion}:$PATH

# print info
echo ""
echo "Building with environment Variables"
echo ""
echo "  DEVELOPER_DIR:  $DEVELOPER_DIR"
echo "  ANDROID_HOME:   $ANDROID_HOME"
echo "  PATH:           $PATH"
echo "  node:           $(node -v)"
echo ""

      

        
        
        
      

    

This gives:

Building with environment Variables

  DEVELOPER_DIR:  /Applications/Xcode_8.3.1.app/Contents/Developer
  ANDROID_HOME:   /Applications/adt/sdk
  PATH:           /usr/local/Cellar/node/7.7.8/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/usr/local/bin:/Applications/adt/sdk/tools:/usr/local/bin/:/Applications/adt/sdk/build-tools/21.1.2:/Users/mles/.fastlane/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin
node -v
  node:           v0.10.48

      

        
        
        
      

    

PATH

, DEVELOPER_DIR

, ANDROID_HOME

Think properly configured, but instead of v7.7.8, it still uses the system version of Node v0.10.48 as set out in PATH

.

What I tried # 2

I used variables:

jenkins.sh:

#!/bin/bash -ve

source config.sh

# print info
echo ""
echo "Building with environment Variables"
echo ""
echo "  DEVELOPER_DIR:  $DEVELOPER_DIR"
echo "  ANDROID_HOME:   $ANDROID_HOME"
echo "  PATH:           $PATH"
echo "  node:           $(node -v)"
echo ""

      

        
        
        
      

    

config.sh

#!/bin/bash -ve
# environment variables
nodeVersion=7.7.8
xcodeVersion=8.3.1
androidSDKVersion=21.1.2

export DEVELOPER_DIR=/Applications/Xcode_${xcodeVersion}.app/Contents/Developer
export ANDROID_HOME=/Applications/adt/sdk
export PATH=/usr/local/Cellar/node/${nodeVersion}/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/usr/local/bin:/Applications/adt/sdk/tools:/usr/local/bin/:/Applications/adt/sdk/build-tools/${androidSDKVersion}:$PATH

      

        
        
        
      

    

The result was the same as in What I've tried #1

: still using the Node v0.10.48 system instead of Node v7.7.8

Question

How can I properly set environment variables PATH

, DEVELOPER_DIR

, ANDROID_HOME

which will only be used within the assembly script?

@tripleee Above, I define Node by calling node: $(node -v)

. In the build script, I run gulp, which runs Ionic / Apache Cordova. Do parentheses match around a node -v

subshell that has its own environment variables?

@Jacob We used nvm before, but we want fewer dependencies. Using nvm requires nvm to be installed on all build machines. We have a Node install standard with brew. This is why I am using /usr/local/Cellar/node/${nodeVersion}

node.
