SonarQube old projects Cleanup command line client

This is a simple java cli program to remove old SonarQube projects, to keep the total number of lines of code below that allowed by the license.

Usage

Prerequisite: java should be installed and on your PATH.

Download sonarqube-cleanup-cli-x.y.zip ZIP file from releases (or SNAPSHOT from packages) and extract it.

Depending your environment system, run sonarqube-cleanup-cli.bat (Windows) or sonarqube-cleanup-cli.sh (Linux) with options.

At min sonarqube-cleanup-cli.[sh|bat] -h http://sonarqube.company.com -l adminUser -p foobar

Options:

usage: sonarqube-cleanup-cli
 -h,--hostUrl <arg>          The SonarQube server URL (or sysenv 'SONAR_HOST_URL').
 -l,--login <arg>            The login or authentication token of a SonarQube user with admin permission (or sysenv 'SONAR_LOGIN').
 -p,--password <arg>         The password that goes with the login username. This should be left blank if an authentication token is being used (or sysenv 'SONAR_PASSWORD').
 
 -d,--dryRun                 Dry run mode, no projects will be deleted (default: false ; or sysenv 'SONAR_CLEANUP_DRY_RUN').
 -y,--yes                    Assume projects deletion without confirmation (default: false ; or sysenv 'SONAR_CLEANUP_YES').
 
 -t,--thresholdCoeff <arg>   The multiplicative coefficient on threshold to calculate LoC to retrieve (default: 2 ; or sysenv 'SONAR_CLEANUP_THRESHOLD_COEFF').
 -n,--numberLocAdd <arg>     The number of LoC in addition to retrieve (default: 0 ; or sysenv 'SONAR_CLEANUP_NUMBER_LOC_ADD').

Explanation about Line Of Code calculation for deletion

The goal of this program is to delete old SonarQube projects, before the total lines of code authorized by license is reached.

When the threshold is reached (~6% of total LoC by default), a email is sent to administrators.

Two options can be configured to customize behavior, depends the needs ; mainly manual or batch/cron/daily execution.

thresholdCoeff : This is the threshold multiplicator coefficient, to calculate the number of lines of code to retrieve in projects deletion ; useful when you want execute this program manually on SonarQube email reception
numberLocAdd : This is the number of line to retrieve in projects deletion, in addition of threshold multiplicator coefficient ; useful when you want execute this program by cron

The combination of both could be done. Think to configure the threshold in http://sonarqube.company.com/admin/extension/license/app with your needs.

Sample: Your license is 100 millions LoC and you want 1 million of limit (for new big project), but keep the email if limit prior to one hundred thousand (in case of problem, if cron program is not correctly executed):

Configure your SonarQube threshold to 100000.
Configure numberLocAdd option to 800000 and let thresholdCoeff to 2 (default value): 100000 x 2 + 800000 = 1000000

Prerequisite

SonarQube v6.2, due to api/components/search_projects usage.

Development process

This project is using Maven as integration tool.

For development/SNAPSHOT build, use:

mvn package

For release build, use (GitHub credentials specially required on command line if 2FA used):

git reset --hard origin/master 
git branch -m next-version 
mvn -B clean release:clean release:prepare -Dusername=yourGitHubLogin -Dpassword=yourGitHubToken

After that, you would have to create pull-request from next-version branch and rebase it on master for next version development.
