How to use Jenkins environment variable in shell script?
提问by Graeme
I want to update a java file with the jenkins build number. I plan on using a shell script to sed the value to the correct build number. I'm currently doing this:
我想用 jenkins 内部版本号更新一个 java 文件。我计划使用 shell 脚本将值发送到正确的内部版本号。我目前正在这样做：
sed -i 's/Version 3.0/Version $BUILD_DISPLAY_NAME/g'
/var/lib/jenkins/jobs/AndroidTest/workspace/xxx/res/values/strings.xml
Why doesn't this work? I'd assume I could just use them directly.
为什么这不起作用？我假设我可以直接使用它们。

As shellcheckwould tell you, expansions don't happen in single quotes. Use double quotes instead:
正如shellcheck会告诉您的那样，扩展不会发生在单引号中。改用双引号：
sed -i "s/Version 3.0/Version $BUILD_DISPLAY_NAME/g" /var/lib/jenkins/jobs/AndroidTest/workspace/xxx/res/values/strings.xml
