This looks like an IntelliJ issue because IntelliJ really wants to configure that task, which kinda makes the whole lazy configuration (register) useless, maybe a better way to fix this, is to simply introduce a default value for the targetDirectory property as it doesn't require everyone to enable publishing again after upgrading

This is not an IntelliJ issue. When you run ./gradlew tasks you also get an exception

[DRSchlaubi]

Then it's a Gradle issue, using register to register tasks is supposed to not evaluate configuration until needed, just listing all tasks, doesn't need to know that

we can also wrap that block in an afterEvaluate {}
