Docker Build can't find GradleWrapperMain on GitLab but works on my laptop

Docker build works on my laptop but on GitLab I get
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Tried a lot of different setups but nothing works...fails at gradlew build...Any ideas are welcome
My .gitlab-ci.yaml

Created a workaround by installing gradle...works now:

WORKDIR /code
# Install Gradle

# Prepare by downloading dependencies
ADD build.gradle /code/build.gradle
ADD src /code/src
RUN echo "Running build"
RUN cd /code
RUN gradle --no-daemon build
EXPOSE $MY_SERVICE_PORT
# Run the service

Logs stucks when deployment is done through teamcity

Recently we migrated to Teamcity deployment from manual process. Ours is java application on linux server.
Whenever deployment is done through Teamcity, logs are stuck i.e. after shutdown log messages nothing else is printed in the logs. Then we run manual stop and start scripts on the server to get the logs running.
Looks like somehow Teamcity locks log file and doesn't release it.
How to overcome it?
In Teamcity, deploy step is defined as below:
REMOTE_PATH="/opt/app/$ARTIFACT/releases/teamcity"
cd $TEAMCITY_REPO_HOME/$ARTIFACT/build/libs
echo "Uploading artifact"
ssh $UAT_HOST -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no "mkdir -p $REMOTE_PATH"
scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $ARTIFACT.jar $UAT_HOST:$REMOTE_PATH
echo "Stopping service"
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $UAT_HOST "sh /opt/app/$ARTIFACT/stop.sh"
sleep 3s
echo "Copying new artifact"
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $UAT_HOST "cp $REMOTE_PATH/$ARTIFACT.jar /opt/app/$ARTIFACT"
sleep 6s
echo "Starting service"
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $UAT_HOST "sh /opt/app/$ARTIFACT/start.sh"

Taking ideas from above comments of Andy Dufresne, I created one deploy script as below:
This single script stops server, takes backup of current artifact, copies new build and then executes start script to start the server.
#!/bin/bash
#check for correct number of arguments
if [ "$#" -ne 1 ]; then
echo "Incorrect number of arguments, exiting..."
exit 1
fi
ARTIFACT=$1
cd "/opt/app/$ARTIFACT"
echo $(pwd)
echo "Stopping service"
bash stop.sh
sleep 3s
echo "Tagging artifact with release"
cp "releases/teamcity/$ARTIFACT.jar" "releases/teamcity/$ARTIFACT`date +'_%y_%m_%d'`.jar"
echo "Deleting old releases"
cd "releases/teamcity" && \
ls | grep -v '/$' | head -n -6 | xargs -d '\n' -r rm -- && \
cd "/opt/app/$ARTIFACT" && \
ls -l "releases/teamcity"
echo "Copying new artifact"
cp "releases/teamcity/$ARTIFACT.jar" .
echo "Starting service"
bash start.sh
sleep 2s
This script is called from team-city in its build steps(previously stopping server, copying artifact and starting server all were done by teamcity explicitly as outlined in the question.)
Now teamcity build step looks concise as under and WORKS as expected(that important !!!):
REMOTE_PATH="/opt/app/$ARTIFACT/releases/teamcity"
cd $TEAMCITY_REPO_HOME/$ARTIFACT/build/libs
echo "Uploading artifact"
ssh -o "StrictHostKeyChecking=no" "$UAT_HOST" "mkdir -p $REMOTE_PATH"
scp -o "StrictHostKeyChecking=no" "$ARTIFACT.jar" "$UAT_HOST:$REMOTE_PATH"
echo "Deploying artifact"
ssh -o "StrictHostKeyChecking=no" "$UAT_HOST" "sh /opt/app/$ARTIFACT/deploy.sh $ARTIFACT"

I do not see Java commands such as java_search or java_element_doc. How can I access them?
I have installed eclim version 2.5, and selected "Java Development" in the installation menu.

bash script to extract jar file and copy the path

I am a PhD student of software testing. I made a script to test all the classes in a specific folder. However to make it fully automatic I would need a script that extract all the jar files in a respective folder and copy both the paths before and after extracting the jar file. For example
If I have AAA.jar at location /Users/mian/Systems/AAA.jar and AAA.jar on extraction create the folders and class org/apple/orange/banana.class then I would like to separately assign org/apple/orange/ to variable VAR1 and /Users/mian/Systems/org/apple/orange/ to VAR2.
The script I have so far is this
#!/bin/bash
STR1="/Users/mian/QualitasCorpus/Systems/freecs/freecs-1.3.20100406/bin/freecs-1.3.20100406/lib/"
STR2="freecs.commands."
for i in $( ls $STR1 ); do
if [[ $i == *.class ]]
then
echo " ################## The Class under test is "$i" ############################" >> result.traces
java yeti.YetiWithDaikon -java -time=10s -nologs -ADFDPlus -testModules="$STR2${i%.*}" >> result.traces
echo " %%%%%%%%%%%%%%%%%%%% The Class is finished testing %%%%%%%%%%%%%%%%%%%%%%%%%" >> result.traces
fi
done
echo "##################################################################################" >> result.traces
echo "############################### End of Folder ####################################" >> result.traces
echo "##################################################################################" >> result.traces
mv result.traces resultsOf"$STR2"traces

This script writes info about the jar file. Names of variables are included in echo.
#!/bin/bash
echo ""
STR1=$(dirname $(realpath $1".jar"))
unzip -qo $1".jar" -d $1 #unzip jar file to working_directory/jarname/
list=$(tree $1 -Rnfi --noreport | grep ".class") #gets the raw .class file list
list=$(echo $list | sed -e 's/'$1'\.//g') #removes the first foldername
list=$(echo $list | sed -e 's/\/class//g') #removes the last .class
list2=$list
list=$(echo $list | sed -e 's/\//\./g') #changes / to .
OLD_IFS=$IFS
IFS=$'\n'" "
echo -e "STR1=\033[34m"$STR1"\033[0m\n"
echo -e "FOLDER=\033[31m"$1"\033[0m\n"
for STR2 in $list
do
echo -e "STR2=\033[32m"$STR2"\033[0m"
done
echo ""
for STR3 in $list2
do
echo -e "STR3=\033[33m"$STR3"\033[0m"
done
echo ""
IFS=$OLD_IFS
Usage:
You have a jar file called freecs.jar. Run it with:
SCRIPTNAME jarfilename
without the .jar extension.
