How can I run multiple commands in package.json scripts?

Question

I'm using detox for end-to-end testing my react-native app. When I try to run yarn detox build -c android.emu.release it does not run the script well cd android ; ./gradlew assembleRelease app:assembleAndroidTest -DtestBuildType=release ; cd -. This script was generated automatically by detox init.

Here is my package.json file:

{
  "detox": {
    /*...*/
    "android.emu.release": {
        "binaryPath": "android/app/build/outputs/apk/release/app-release.apk",
        "build": "cd android  ./gradlew assembleRelease app:assembleAndroidTest -DtestBuildType=release ; cd -", //<<<<<<<<<<<
        "type": "android.emulator",
        "device": {
          "avdName": "NexusOneAPI29"
        }
      }
    /*...*/
  },
  /*...*/
}

I am struggling to run yarn detox build -c android.emu.release for instance. If

Which symbol/char do I need to use to concat commands instead of `;` on detox?

The main error I believe is: The system cannot find the path specified. extracted from below.

$ yarn detox-build                                                  
yarn run v1.21.1

I know you are targeting Android, but what envrioment are you running the npm scripts from? Have you tried using && instead of ;? — Brian H.

I did try && but it does not work on Powershell on Windows :'( — ofundefined

@AlexandreLage - Yes, you're right, I forgot that I created an alias for the which command in Powershell some time ago. You'd need to run get-command cmd.exe instead. However, it's not relevant now as your issue is very different from the original question. — RobC

You should use && to run multiple commands on any platform and any shell from npm scripts. You would expect it does not work on powershell but it does actually.

[npm] doesn't have the exact same semantics for && (it executes the second command regardless of the success of the first), but it does work to string together multiple commands on a line.

Thanks. You are right. I updated my question as I realized the problem is not using && with npm scripts but with detox script. Voted you up
