title: Sonarqube don't recognize base directory
body: <p>I have the next problem. I'm developing a project in java and create sonar.properties file to use SonarQube (v6.7.2). My project have two modules. The project structur is:</p>
  
  <p>my-project<br/>
  &nbsp;&nbsp;|--core-utils<br/>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|--src<br/>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|--target<br/>
  &nbsp;&nbsp;|--pdf-utils<br/>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|--src<br/>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|--target<br/></p>
  
  <p>And sonar.properties is:</p>
  
  <p>First module<br/>
  sonar.moduleKey=com.app.core.pdf:pdf-utils<br/>
  sonar.projectBaseDir=/var/lib/jenkins/workspace/MyProject/pdf-utils<br/>
  sonar.projectKey=com.app.core.pdf:pdf-utils<br/>
  sonar.projectName=pdf-utils<br/>
  sonar.projectVersion=0.90.0-SNAPSHOT<br/>
  sonar.sources=/var/lib/jenkins/workspace/MyProject/pdf-utils/src/main/java<br/>
  sonar.working.directory=/var/lib/jenkins/workspace/MyProject/pdf-utils/target/sonar<br/>
  sonar.java.binaries=/var/lib/jenkins/workspace/MyProject/pdf-utils/target/classes<br/></p>
  
  <p>Second module<br/>
  sonar.moduleKey=com.app.core:core-utils<br/>
  sonar.projectBaseDir=/var/lib/jenkins/workspace/MyProject/core-utils<br/>
  sonar.projectKey=com.app.core:core-utils<br/>
  sonar.projectName=core-utils<br/>
  sonar.projectVersion=0.90.0-SNAPSHOT<br/>
  sonar.sources=/var/lib/jenkins/workspace/MyProject/core-utils/src/main/java<br/>
  sonar.working.directory=/var/lib/jenkins/workspace/MyProject/core-utils/target/sonar<br/>
  sonar.java.binaries=/var/lib/jenkins/workspace/MyProject/core-utils/target/classes<br/></p>
  
  <p>Main module<br/>
  sonar.host.url=<a href="http://localhost:9000/sonar" rel="nofollow noreferrer">http://localhost:9000/sonar</a><br/>
  sonar.java.source=1.6<br/>
  sonar.java.target=1.6<br/>
  sonar.moduleKey=com.app.core:core-all<br/>
  sonar.modules=com.app.core:core-utils,com.app.core.pdf:pdf-utils<br/>
  sonar.projectBaseDir=/var/lib/jenkins/workspace/MyProject<br/>
  sonar.projectKey=com.app.core:core-all<br/>
  sonar.projectName=core-all<br/>
  sonar.projectVersion=DEV-SNAPSHOT<br/>
  sonar.sourceEncoding=UTF-8<br/></p>
  
  <p>Then runs SonarScanner and the result is:</p>
  
  <p>The base directory of the module 'com.app.core:core-utils' does not exist: /var/lib/jenkins/workspace/MyProject/com.app.core:core-utils</p>
  
  <p>I don't know why do this if I put base directory for each module.</p>
  
  <p>Thanks!!</p>
