UselessCallOnNotNull doesn't report

[CuiLam]

I wrote val testList = listOf("string").orEmpty() in my code, but detekt can not find it.

Can you please take a look at my comment on #2036 and see if it similarly describes your issue?

[CuiLam]

yes, it 's sinilarly

[CuiLam]

so now what can I do

[3flex]

We need to write docs so users know how to run detekt so all rules run as expected.

We're aware, just need to find the time to work on it.

If using Gradle try running detektMain task.

When i running detektMain tash, it report

so all rules work well in v1.1.1. Issues for example #2043 are caused by users don't know how to run it correctly even for android project. Is that right? @3flex

[3flex]

@CuiLam those errors are Gradle script compilation errors which don't look related to detekt itself, are you using Gradle to build your project or just trying to run the detekt Gradle task?

@dive5617 basically yes. We need to make a couple more improvements then write docs.

I can't run detekyMain in my android project, so how can I do that

[schalkms]

#2259 shows how to run detektMain on Android.
