Build fix

I fixed the build by adding the necessary dependencies into a local repository with the following commands

```
mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=openapi \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/openapi.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=util \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/util.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=extensions \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/extensions.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=annotations \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/annotations.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=idea \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/idea.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=picocontainer \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/picocontainer.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

mvn deploy:deploy-file \
    -DgroupId=local.com.intellij \
    -DartifactId=trove4j \
    -Dversion=12.1.6 \
    -Dfile=/Applications/IntelliJ\ IDEA\ 12.app/lib/trove4j.jar \
    -Dpackaging=jar \
    -Durl=file:///Users/admin/dev/repos/github/sonar-intellij-plugin_NEW/intellij-repo

```
