Cannot host Spring web app war on Tomcat using Jenkins plugin

Can you help me to deploy my project to Tomcat container using Jenkins? In build step I use script file buildscript-no-launch.bash:

#!/bin/sh

echo Removing old resources...
cd Maitinimas-back/src/main/resources/public
rm -r -f ./*
echo "Old resources removed."

echo Building react app...
cd ../../../../../Maitinimas-front/

# Check if node_modules/ exists, if not run npm install
if [ ! -d "node_modules" ]; then
    echo "node_modules not found. Running npm install..."
    npm install
    if [ $? -ne 0 ]; then
        echo "npm install failed. Exiting."
        exit 1
    fi
else
    echo "node_modules exists. Skipping npm install."
fi

# Run npm build and check for errors
if npm run build | grep "Failed\|failed\|error\|Error\|not found"
    then echo Npm build failed, try npm install first
    exit 1
else
    echo Npm build completed
fi

echo Copying build to target...
cd ../Maitinimas-back/src/main/resources/public/
cp -r ../../../../../Maitinimas-front/build/* .
echo "Build copied."

echo Maven clean package...
cd ../../../../
mvn clean package -DskipTests

#!/bin/sh

echo Removing old resources...
cd Maitinimas-back/src/main/resources/public
rm -r -f ./*
echo "Old resources removed."

echo Building react app...
cd ../../../../../Maitinimas-front/

# Check if node_modules/ exists, if not run npm install
if [ ! -d "node_modules" ]; then
    echo "node_modules not found. Running npm install..."
    npm install
    if [ $? -ne 0 ]; then
        echo "npm install failed. Exiting."
        exit 1
    fi
else
    echo "node_modules exists. Skipping npm install."
fi

# Run npm build and check for errors
if npm run build | grep "Failed\|failed\|error\|Error\|not found"
    then echo Npm build failed, try npm install first
    exit 1
else
    echo Npm build completed
fi

echo Copying build to target...
cd ../Maitinimas-back/src/main/resources/public/
cp -r ../../../../../Maitinimas-front/build/* .
echo "Build copied."

echo Maven clean package...
cd ../../../../
mvn clean package -DskipTests

This one works well. But then I use post-build step Deploy war/ear to a container

It gets deployed:

But once I open it then it's not found:

Tomasm21OP•2mo ago

frontend homepage is /Maitinimas But http://localhost:2020/Maitinimas-0.0.1/Maitinimas and http://localhost:2020/Maitinimas also does not work. In application.properties I have server.servlet.context-path=/Maitinimas. -------------------------------- But if in the build bash file I use embedded tomcat:

//.....
echo Copying build to target...
cd ../Maitinimas-back/src/main/resources/public/
cp -r ../../../../../Maitinimas-front/build/* .
echo "Build copied."

echo Maven clean package...
cd ../../../../
mvn clean package -DskipTests

#echo Starting tomcat on port 8081...
mvn org.codehaus.cargo:cargo-maven2-plugin:1.7.7:run -Dcargo.maven.containerId=tomcat9x -Dcargo.servlet.port=8081 -Dcargo.maven.containerUrl=https://repo1.maven.org/maven2/org/apache/tomcat/tomcat/9.0.40/tomcat-9.0.40.zip

//.....
echo Copying build to target...
cd ../Maitinimas-back/src/main/resources/public/
cp -r ../../../../../Maitinimas-front/build/* .
echo "Build copied."

echo Maven clean package...
cd ../../../../
mvn clean package -DskipTests

#echo Starting tomcat on port 8081...
mvn org.codehaus.cargo:cargo-maven2-plugin:1.7.7:run -Dcargo.maven.containerId=tomcat9x -Dcargo.servlet.port=8081 -Dcargo.maven.containerUrl=https://repo1.maven.org/maven2/org/apache/tomcat/tomcat/9.0.40/tomcat-9.0.40.zip

Then the tomcat server starts in the terminal and I can succesfully load my web app on http://localhost:8081/Maitinimas I have installed Apache Tomcat/9.0.95 on my PC on Windows. And it's really strange that Jenkins post-build step is not working as it should. I don't know why. Maybe the step works because the project is passed to the Tomcat. And the app is in the list. But it can't be found. I don't know particular reason.
