Executing bash script in gradle

Question

I am doing functional testing with geb.

My application is deployed using virgo and uses HSQLDB to store data. I would like to perform tests on this working version of application, but I would like to start with empty database, every time I run webtests.

I wrote a simple bash script

#!/bin/sh
rm -rf $VIRGO_HOME/aresdb*
$VIRGO_HOME/bin/shutdown.sh &
sleep 10
$VIRGO_HOME/bin/startup.sh &

which removes the database and restarts virgo.

However, when I add it to my build.gradle task executing command never ends.

task cleanDB(type: Exec) {
    commandLine './clean.sh' 
}

Why is it this way? When I run this script in console it returns quickly (but virgo still writes to the console).

I have tried to run it in separate thread, but I encountered following error:

task cleanDBThread()<<{
    def cleanDBThread1 = Thread.start {
         cleanDB.execute()
    }
    sleep 10000
    println "wake up!"
}

Exception in thread "Thread-32" java.lang.IllegalStateException:
Cannot start long running operation, as the task artifact state cache
(/home/tomasz/ares/.gradle/1.0-milestone-9/taskArtifacts) has not been locked.

I also tried setting 'create-drop' in hibernate configuration, but it also requires restarting virgo. Even redeploying the application does not help.

What should I do to run webtests with empty database?

Answer 1

That's weird

I created a task

task callCL(type: Exec) {
    commandLine './cl.sh'
}

that calls cl.sh file

#!/bin/sh
echo "starting "
./acl.sh &
sleep 10
./acl.sh &

that call acl.sh

#!/bin/sh
echo "I am not doing anything"

and it worked! but one thing though, when you add ./acl.sh ampersand character & you're calling the task from a different thread that started gradle, and kinda looks like it's hanging. I would remove the & from your calls to shutdown and start like this

#!/bin/sh
rm -rf $VIRGO_HOME/aresdb*
$VIRGO_HOME/bin/shutdown.sh
$VIRGO_HOME/bin/startup.sh

anyways you want to wait in the same thread from shutdown to start, and no need to call sleep too!
