I don't know why I keep on getting mysterious errors in gradle like this:

e: .../app/build.gradle.kts:10:45: Unresolved reference: util
e: .../app/build.gradle.kts:11:65: Unresolved reference: newDataInputStream

I updated to gradle 7.3.3 and android plugin 7.0.4...

[dave08]

It's for these two lines:

val localProps: java.util.Properties = java.util.Properties()
localProps.load(project.rootProject.file("my-local.properties").newDataInputStream())

If you have the java-base plugin (or one that applies it) applied, then java is an extension.
The java extension wins over the java package.
You instead need to import the class you want to use as there it is unambiguous that you want the package, not the extension.

[Vampire]

The java extension does not have a util property which is what the error is telling you

[dave08]

🤕... Thanks for the explanation! They really should have given that another name... or at least AndroidStudio should be a bit smarter!

[Vampire]

Yes, AS and IJ should be a bit smarter about that, report it to JetBrains so it can get fixed.
But another name is not really necessary, because what you do is non-idiomatic. 🙂

[Vampire]

In an idiomatic build, build scripts itself should not contain logic, but be as declarative as possible.
Custom logic should be done in custom plugins and custom tasks, and then you don't have that problem. 🙂
And naming the extension java is just natural.

[Vampire]

Besides that, when the naming was done, no Kotlin DSL existed and in the Groovy DSL it does not lead to a problem.

[dave08]

Yeah, true... but in this case, a whole plugin for those two lines? It's basically to not have to commit the release keys to Git...

[Vampire]

Well, almost no build is fully idiomatic, just speaking about a perfect world. 🙂

[Vampire]

And you just have to add the import and all is well and better readable anyway.

[Vampire]

I also don't know why IJ adds FQCNs anyway instead of using imports.

[dave08]

Yeah, I was wondering about that too 🤔...
