Hello iOS developer here 😄. I'm trying to build an Swift Package plugin that runs a gradle script to build my kmm shared lib;
Basically boils down to this (just checking the gradle version here to see if its working)

.prebuildCommand(displayName: "Gradle Build (path: \(projectRoot.description))", executable: projectRoot.appending(subpath: "gradlew"), arguments: ["-v"], environment: ["JAVA_HOME": javaHome], outputFilesDirectory: context.pluginWorkDirectory)]

Gradle seems to take issue, saying ERROR: JAVA_HOME is set to an invalid directory
Now, the JAVA_HOME is set to use /usr/libexec/java_home, which points to a java 11 version i've installed through homebrew. For some reason however, gradle expects the JAVA_HOME to point to the java provided by Android Studio (which I don't want, because I want to run this on CI as well). What am I missing here?

[Jerry]

Ah, got it; had to trim the whitespaces and newlines from the javaHome dir 🤦

@Jerry Nice approach! Are you using the approach productively? I haven't gotten it to work yet and would be happy to see an example. I think my problem is related to the sandbox.

[Jerry]

No, unfortunately I abandoned pursuing this approach. I can't recall why exactly.

We ended up having the KMM module as a git submodule in our iOS project, and just building the framework in a build phase script.
We still had to jump some hoops to get it to build on our CI (Xcode Cloud), mostly documented here: https://stackoverflow.com/questions/72578619/building-kotlin-multiplatform-app-with-xcode-cloud/76092736#76092736

Thanks a lot Jerry, we've switched recently to a monorepo which simplifies the process of building the shared library a lot
