Custom linting lib in android

Question

My team and I develop Android apps and have decided on coding guidelines that all should follow. I therefore started implementing custom lint rules as per the following links:

• Post written by Matt Compton
• Git Repo

The problem that I'm having is actually implementing these lint rules on a project basis. When I run ./gradlew clean build test install , as specified the rules apply and all is well. However when I build the aar library with ./gradlew aarWrapper:assemble and add it to my libs folder the linting does not work.

I added the following to my build.gradle file to add the library

repositories {     flatDir {             dirs 'libs'         } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile(name: 'aarWrapper-debug', ext: 'aar') } 

I'm not sure what I'm missing but when I run ./gradlew lint it runs the linter but not with my custom rules... Any help, tips or advice is greatly appreciated.

Here is the terminal output when running gradle.

EDIT 3 In addition to the links above I found this post written by Jason Atwood. We too have a CI server running jenkins in which we can run our checks and inform developers of errors based off of our lint rules. This works great, however, it is one step to far. It would be much more valuable and time save to run lint checks from the library when running our projects out of Android Studio, instead of committing our code only to find out that our project breaks rules.

I have written a post on how to add and integrate custom lint rules to your android app, you can have a look. It also has links to github repos showing how its done in an android project. Link to post

The easiest way for me was to set ANDROID_LINT_JARS path in the gradlew file and point it to the custom lint jar which is checked in to VCS system, so that you can run it locally as well before pushing the code. Hope it helps.
