I refer to setting Export schemas in the documentation, But it failed, the error is as follows: The following is my Gradle configuration:

    RoomSchemaArgProvider(File schemaDir) {
        this.schemaDir = schemaDir
    }

    @Override
    Iterable<String> asArguments() {
        // Note: If you're using KSP, you should change the line below to return
        // ["room.schemaLocation=${schemaDir.path}"]
        return ["-Aroom.schemaLocation=${schemaDir.path}"]
    }
}

I am basically sure that it is an error caused by setting Export schemas. When I set exportSchema = false, the program can run normally. Sorry my settings file is a bit messy, but like I said, it works.

CodePudding user response：

Convert string like this:

 return ["-Aroom.schemaLocation=${schemaDir.path}".toString()]
