I'm not able to run the MVN goals through shell script - bash

Question

I just used the below shell script in Post Build activity in JENKINS "Execute Shell" cmd
#!/bin/bash
mvn --version
export M2_HOME=/opt/maven/maven-3.3.3 # your Mavan home path
export PATH=$PATH:$M2_HOME/bin
mvn --version
echo $HOME
echo $WORKSPACE
file=$WORKSPACE/XXXX/XXXX-reports
cd $file
cp XXXX-1.html test.html
fail=`grep "test-method.*FAIL" results.xml | sed -e 's/^.*test-
instance-name="\(.*\) ' | tr '\n' ','`
echo $fail
count=0
while [ $count -lt 5 ]
do
if [ ! -z "$fail" -a "$fail" != " " ];
then
echo `$M2_HOME/bin/mvn clean test -f ../../pom.xml -DInclude=${fail}`
cp XXXX-report.html ReReport_$count.html
retry=`expr $count + 1`
fi
done
In the above shell script I'm trying to run the mvn command and continuing to run 5 times to increase pass count in UNIT script execution.
But It's not working. It's failed to execute the maven goals. So, I just comment the executable and added echo to debug.
But no luck.
Any leads

Answer 1

I suggest that you use this following script that modifies yours. Add your parameters there.
The product log file: mvn_jenkins.log will allow you to easily find problems as suggested by mjuarez:
#!/bin/bash
MVNCMD=$(command -v mvn)
MVNPARAMS=" -version" # replace with your appropriate params
LOGFILE="mvn_jenkins.log"
COUNT=0
while [ $COUNT -lt 5 ]; do
echo "Execute: $MVNCMD $MVNPARAMS" >> $LOGFILE
echo "-------" >> $LOGFILE
$MVNCMD $MVNPARAMS 2>&1>> $LOGFILE
echo "" >> $LOGFILE
COUNT=$((COUNT + 1))
done
Explanation:
MVNCMD=$(command -v mvn): put the full qualified name of maven execute file in MVNCMD var
$MVNCMD $MVNPARAMS 2>&1>> $LOGFILE: Execute mvn command with parameters and redirect error output messages (2) and regular output messages (1) to the log file.
About your maven parameters I don't understand why you use -DskipTests=true.
