Please use the ctools-installer from http://github.com/pmalves/ctools-installer to install Saiku-Reporting
ATTENTION: If you have no pentaho-reporting-engine-classic-extensions-cda-xxx.jar in your pentaho/web-inf/lib directory you will not be able to export a PRPT-Report to your solution repository. Same applies if you have the "wrong" version of that extension installed. To be sure that the export works, you should replace the pentaho-reporting-engine-classic-extensions-cda-xxx.jar in pentaho/web-inf/lib with the one that we provide (without warranty that your other solutions will still work).
First build the UI project from git@github.com:Mgiepz/saiku-adhoc-ui.git by checking it out and running: mvn clean package install:install-file -Dfile=target/saiku-adhoc-ui-2.2-SNAPSHOT.war -DgroupId=org.saiku -DartifactId=saiku-adhoc-ui -Dversion=2.2-SNAPSHOT -Dpackaging=war
Then checkout https://github.com/Mgiepz/saiku-adhoc.git, cd into saiku-adhoc-core and run: mvn clean install
Then if all went well cd into saiku-adhoc-plugin and run: mvn clean package
In the resulting "target" directory you will find a saiku-adhoc-plugin-2.2-SNAPSHOT.zip file.
