I created my first pipeline yesterday and I wanted to replace a placeholder in my bundle.gradle file with the CIRCLE_BUILD_NUM environment variable. The only method I found find was writing my own ‘sed’ command and executing the regex in a run statement. This worked fine to get up and running, since…

I do not know of a CircleCI specific solution, but generally speaking, if you need to replace a term in a Git repo you can combine git grep and sed - run: name: Replace build id command: | git grep -l '_buildNum' | xargs sed -i "s/_buildNum/${CIRCLE_BUILD_NUM}/g" That would replace a…

I was trying to replace all variables based on some type of identifier (i.e. a variable name encapsulated with ${}) similar to this Azure DevOps task. You would have to specify the file, but would prevent you from having to run this command once for each and every variable you want to insert. I’m g…

@mike Probably a better question: what is the recommended way to replace environment variables within a CircleCI pipeline?

You’re putting yourself through a lot of work when you could just read in the value. Don’t make risky sed calls when you don’t have to. def buildNumber = System.getenv("CIRCLE_BUILD_NUM") buildNumber will be null if the environment variable doesn’t exist, so adjust your build logic accordingly.

You shouldn’t have to, no. Try it out locally by just printing the variable value from your build.gradle and debugging on your own machine. There’s nothing special about Circle’s bash environment export CIRCLE_BUILD_NUMBER=1 ./gradlew classes # verify the build number appears with your println expo…

Returns null for me in build gradle even though the output in the build showing the ENVs has that value set. Is there something else I need to do in my gradle to somehow get ENV vars detectable in gradle build script?
