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. Extract this into pentaho-solutions/system There might be some confusion with the libraries responsible for CDA-Access. Have a look at you pentaho/web-inf/lib directory and check if there is a file that begins with pentaho-reporting-engine-classic-extensions-cda-... Also look at the version number of the reporting engine. If the reporting-engine has a version 3.8.x download the jar file from http://github.com/Mgiepz/saiku-adhoc/tree/master/lib and put it in the lib-folder if the reporting engine is a newer trunk-version, copy the jar file from the plugin's lib folder to web-inf/lib For questions join us at ##saiku on freenode
