bash 使用 shell 脚本将环境变量注入 Jenkins 构建过程

Inject Environment variables into a Jenkins build process with a shell script

提问by mles

The starting situation

开局情况

I have a Jenkins build Project where I'm doing almost everything by calling my build script (./jenkins.sh). I'm building a Cordova Project, which is dependent on certain versions of Node and Xcode. I'm running the builds on Macs with the latest MacOS Sierra.

我有一个 Jenkins 构建项目，我通过调用我的构建脚本 ( ./jenkins.sh)来完成几乎所有事情。我正在构建一个 Cordova 项目，它依赖于某些版本的 Node 和 Xcode。我正在使用最新的 MacOS Sierra 在 Mac 上运行构建。

So far I'm setting the environment variables in the Jenkins Build with the EnvInject Plugin(https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin):

到目前为止，我正在使用 EnvInject 插件（https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin）在 Jenkins Build 中设置环境变量：

The Goal

目标

I want to have the environment variables also set by the build script instead of in the Jenkins Build. This way the environment variables are also in version control and I don't have to touch the Jenkins Build itself.

我希望环境变量也由构建脚本设置，而不是在 Jenkins 构建中设置。这样环境变量也在版本控制中，我不必接触 Jenkins Build 本身。

Basically I need to rebuild the logic of the EnvInject Plugin with bash.

基本上我需要用 bash 重建 EnvInject 插件的逻辑。

What I've tried #1

我试过的#1

Within my jenkins.shbuild script I've set the environment variables with export

在我的jenkins.sh构建脚本中，我设置了环境变量export

jenkins.sh:

詹金斯.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 yields:

这产生：

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_HOMEseems to be set correctly, however it is still using the system version of node v0.10.48 instead of v7.7.8 as set in PATH.

PATH, DEVELOPER_DIR,ANDROID_HOME似乎设置正确，但是它仍然使用节点 v0.10.48 的系统版本，而不是在 中设置的 v7.7.8 PATH。

What I've tried #2

我试过的#2

I've sourced the variables:

我已经找到了变量：

jenkins.sh:

詹金斯.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

配置文件

#!/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 system node v0.10.48 instead of node v7.7.8

结果与以下相同What I've tried #1：仍然使用系统节点 v0.10.48 而不是节点 v7.7.8

The question

问题

How can I set the PATH, DEVELOPER_DIR, ANDROID_HOMEenvironment variables properly to be used only within the build script?

如何正确设置PATH, DEVELOPER_DIR,ANDROID_HOME环境变量以仅在构建脚本中使用？

@tripleee Above I'm determining node by calling node: $(node -v). In the build script I'm running gulp which triggers Ionic / Apache Cordova. Do the brackets around node -vstart a subshell which has it's own environment variables?

@tripleee 以上我通过调用node: $(node -v). 在构建脚本中，我正在运行 gulp，它会触发 Ionic/Apache Cordova。括号周围是否node -v启动了一个子shell，它有自己的环境变量？

@Jacob We have used nvm before, but we want to have less dependencies. Using nvm requires to install nvm on all build machines. We have a standard of installing node with brew. That's why I'm using /usr/local/Cellar/node/${nodeVersion}as path to node.

@Jacob 我们之前使用过 nvm，但我们希望减少依赖。使用 nvm 需要在所有构建机器上安装 nvm。我们有一个用 brew 安装节点的标准。这就是我使用/usr/local/Cellar/node/${nodeVersion}作为节点路径的原因。

This doesnt look like an environment variable issue. It looks like a permissions issue. The user executing the script is either:

这看起来不像是环境变量问题。看起来像是权限问题。执行脚本的用户是：

• not able to read the /usr/local/Cellar/node/7.7.8/bin directory, or
• not able to read the node executable from that directory, or
• not able to execute the node executable from that directory

• 无法读取 /usr/local/Cellar/node/7.7.8/bin 目录，或
• 无法从该目录读取节点可执行文件，或
• 无法从该目录执行节点可执行文件

In order to test, become that user on the machine and execute the node command against the full path:

为了测试，成为机器上的那个用户并针对完整路径执行节点命令：

/usr/local/Cellar/node/7.7.8/bin/node -v

or, if you need to, change the script to avoid using PATH lookups (Im suggesting this for diagnosis only, not as a solution):

或者，如果您需要，更改脚本以避免使用 PATH 查找（我建议这仅用于诊断，而不是作为解决方案）：

echo "  node:           $(/usr/local/Cellar/node/7.7.8/bin/node -v)"

If you are still at a loss, try this line:

如果您仍然不知所措，请尝试以下行：

echo "  node:           $(sh -c 'echo $PATH'; which node)"
