I am using jenkins CI to build my project. After the build I had post steps shell script copy the war to WSO2 application servers /repository/deployment/server/webapps/ folder. But what I observed was sometimes ( not always ), the server failed to redeploy the web application. Most of the times the web application would be redeployed using the new war file copied by jenkins into the webapps folder. But sometimes this did not happen. At such times the only solution was to stop the wso2as server, delete the web applications folder leaving only the new war file in wenapps directory and start the wso2as server again. This deployed the new war file and testing could proceed.
But we need to run automated selenium tests. So for the tests to run we need the new war file to be deployed reliably on every jenkins build.
So I wrote a little script in the jenkins post step like below :
#!/bin/bash
/home/kk/wso2as-5.0.1/bin/wso2server.sh stop &&
sleep 1m &&
rm -rf /home/kk/wso2as-5.0.1/repository/deployment/server/webapps/Duster_App1* &&
cp /home/kk/.jenkins/workspace/Dusters_App1/target/Duster_App1-${MAVEN_VERSION}.war /home/kk/wso2as-5.0.1/repository/deployment/server/webapps/Duster_App1.war &&
/home/kk/wso2as-5.0.1/bin/wso2server.sh start &&
echo Starting wso2as
This script runs. The wso2as server is stopped, the webapp folder is deleted, the new war file is copied corectly in place, I get the 'Starting wso2as' message on jenkins console output, BUT the wso2as server does not start. It remains in the stopped state. I introduced the sleep 1m line after the wso2server.sh stop command thinking the server may be taking time to shut down and hence fails to start again by the time the wso2server.sh start command is run. But no. The server is stopped cleanly before the start command is run as I have verified by following the log file as well as by ps aux command.
So what could be preventing the server from starting again?
