What is the correct way to set up an Android project using submodules for use with the sonarqube gradle plugin?

What is the correct way to set up an Android project using submodules for use with the sonarqube gradle plugin? Google wasn't my friend, but I might have missed something basic. (I'm looking for sonarbeb issues related to android build directories and submodules. No useful results.)

At a very high level, I am working with an Android project with the following structure.

git_repository
|----- android_project
  |--- app
  |--- SDK
    |- api

git_repository contains README.md and other top-level files including android_project. The android_project contains the app as well as the git submodule in the SDK. This git submodule contains the api code for the application to execute.

The problem is when I try to start sonarqube it looks like you are looking for files / directories that don't exist. I don't have this problem with a simpler minimal project. I am planning on creating a minimal project that uses submodules on Monday, but I want this question to go out the door before I leave for the weekend.

$ ./gradlew clean sonarqube
* snip *
:sonarqube
Invalid value for sonar.java.test.libraries
:sonarqube FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':sonarqube'.
> No files nor directories matching '/Users/my_username/git_repository/android_project/app/build/intermediates/dependency-cache/debug'

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or -- debug option to get more log output.

BUILD FAILED

This gradle task does not work in macOS / Android Studio command line setup, but the end goal is to set up a config that works with Jenkins. My settings.gradle and build.gradle files follow them. It is clear that I am doing something wrong.

git_repository / android_project / settings.gradle full list

include ':app', ':api'
project(':api').projectDir = new File('SDK/api')

git_repository / android_project / build.gradle full list

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

apply plugin: 'org.sonarqube'

allprojects {
    repositories {
        jcenter()

    tasks.withType(JavaCompile) {
        options.encoding = 'UTF-8'

yes, it is a bit tricky for a multi-module project, which is achieved with appropriate wildcards.

do the following:

  • in the main module which contains all the submodules, the sonarqube.gradle file enter image description here

  • in build.gradle file of main module add maven plugin and class dependencies enter image description here

here is an example of the above two files:

sonarqube.gradle

apply plugin: "org.sonarqube"

sonarqube {
//noinspection GroovyAssignabilityCheck
    properties {
//noinspection GroovyAssignabilityCheck
        property "sonar.projectName", "appar"
//noinspection GroovyAssignabilityCheck
        property "sonar.projectVersion", "1.0"
//noinspection GroovyAssignabilityCheck
        property "sonar.analysis.mode", "publish"
//noinspection GroovyAssignabilityCheck
        property "sonar.language", "java"
//noinspection GroovyAssignabilityCheck
        property 'sonar.sourceEncoding', "UTF-8"
//noinspection GroovyAssignabilityCheck
        property "sonar.sources", "./src/main"
   // noinspection GroovyAssignabilityCheck
        property "sonar.exclusions", "src/main/java/com/appar/model/**, **/*Entity.java"
//noinspection GroovyAssignabilityCheck
        property "sonar.host.url", "http://192.168.21.33:9000"
//noinspection GroovyAssignabilityCheck
        property "sonar.login", "admin"
//noinspection GroovyAssignabilityCheck
        property "sonar.profile", "fulllint"
//noinspection GroovyAssignabilityCheck
        property 'sonar.import_unknown_files', true
//noinspection GroovyAssignabilityCheck
        property "sonar.android.lint.report", "./build/outputs/lint-results-debug.xml"
//noinspection GroovyAssignabilityCheck
        property "sonar.password", "admin"
 //noinspection GroovyAssignabilityCheck
        property "sonar.java.binaries", "build/"

    }
}

build.gradle

buildscript {
    repositories {
        jcenter()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath "org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.0.1"
        classpath 'com.dicedmelon.gradle:jacoco-android:0.1.1'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

then apply with sonarqube.gradle in build.gradle of individual modules

here is an example build.gradle of one of the following modules:

apply plugin: 'com.android.library'
apply from: '../sonarqube.gradle'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled = true
        }
    }
}

dependencies {
    compile project(':java-library')

    testCompile 'junit:junit:4.12'
    testCompile "org.robolectric:robolectric:3.1.4"
}


just put this line along with all other applicable lines as shown in the above file

apply from: '../sonarqube.gradle'

enter image description here

after you apply sonarqube.gradle to all build.gradle files in additional modules.

just run the command

./gradlew sonarqube

Trust me that the project will be successfully created and run on the sonarqube server and error results will be shown.

if you are using findbugs to make the project fail before pushing or build fail because findbugs needs bytecode to parse.

And don't use the property

//noinspection GroovyAssignabilityCheck
            property "sonar.projectKey", "appar_app"

This is the sonar.projectKey property. This is used by SonarQube to define each project (or module) in the sonar database. Therefore, if all your modules have the same projectKey value, SonarQube will update one separate project in its database. Don't worry, this property is automatically set with the folder name for each module.
