Bootstrap quarkus app (with jabbaw & mvnw) from almost nothing

snippet.markdown

Make a directory for you project

mkdir YOU_PROJECT_NAME
cd YOU_PROJECT_NAME

Install "install-less" jabbaw (java version manger) https://github.com/Jabba-Team/jabba/blob/main/jabbaw.md

curl -sLO https://raw.githubusercontent.com/Jabba-Team/jabba/main/jabbaw
chmod +x jabbaw
curl -sLO https://raw.githubusercontent.com/Jabba-Team/jabba/main/jabbaw.ps1

echo "temurin@21" > .jabbarc

install mvnw from bash (this installs the most recent non alpha/beta version of maven)

#!/bin/bash



# Step 1: Download the Maven Wrapper scripts
curl -o mvnw https://raw.githubusercontent.com/apache/maven-wrapper/master/maven-wrapper-distribution/src/resources/mvnw
curl -o mvnw.cmd https://raw.githubusercontent.com/apache/maven-wrapper/master/maven-wrapper-distribution/src/resources/mvnw.cmd


# Step 2: Download the Maven Wrapper JAR
mkdir -p .mvn/wrapper/

LATEST_VERSION_MVNW=$(curl -s https://repo1.maven.org/maven2/org/apache/maven/wrapper/maven-wrapper/maven-metadata.xml  \
| grep -oP "(?<=<version>)[^<]+" \
| grep -vE 'alpha|beta|rc' \
| tail -1)
curl -o .mvn/wrapper/maven-wrapper.jar https://repo1.maven.org/maven2/org/apache/maven/wrapper/maven-wrapper/$LATEST_VERSION_MVNW/maven-wrapper-$LATEST_VERSION_MVNW.jar

# Step 3: Query the latest stable Maven version
LATEST_VERSION_MVN=$(curl -s https://repo1.maven.org/maven2/org/apache/maven/apache-maven/maven-metadata.xml \
| grep -oP "(?<=<version>)[^<]+" \
| grep -vE 'alpha|beta|rc' \
| tail -1)


# Step 4: Create the maven-wrapper.properties file with the latest version
cat > .mvn/wrapper/maven-wrapper.properties <<EOL
distributionUrl=https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/$LATEST_VERSION_MVN/apache-maven-$LATEST_VERSION_MVN-bin.zip
EOL

# Step 5: Make the mvnw script executable
chmod +x mvnw

# Step 6: enhance mvnw experience with jabba by adding to mvnw script (before: # OS specific support ...):
sed -i.bak '/^# OS specific support/i \
[ -f ./.jabbarc ] && [ -f ./jabbaw ] && export $(./jabbaw env | grep JAVA_HOME)\
' mvnw

echo "Maven Wrapper installed successfully!"
echo "Maven version $LATEST_VERSION will be used."
echo "You can now use './mvnw' to run Maven commands."

Now check the versions (if they are correct):

./jabbaw ./mvnw -v

Apache Maven 3.9.9 (8e8579a9e76f7d015ee5ec7bfcdc97d260186937)
Maven home: /home/stephan/.m2/wrapper/dists/apache-maven-3.9.9-bin/33b4b2b4/apache-maven-3.9.9
Java version: 21.0.4, vendor: Eclipse Adoptium, runtime: /home/stephan/.jabba/jdk/temurin@21.0.4

Create quarkus project with jabbaw & mvnw (quakuse plugin need current version of java & maven)

./jabbaw ./mvnw io.quarkus.platform:quarkus-maven-plugin:3.13.2:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=getting-started \
    -Dextensions='rest'

Now the files are in getting-started, you have to move them to the parent dir, so that your mvnw & jabbaw work correcly

cd CREATED_DIR_;  cp -R pom.xml README.md src/ ..
cd ..; rm -r CREATED_DIR_

Start quakus dev mode

./jabbaw ./mvnw quarkus:dev

Often a custom port is needed:

./jabbaw ./mvnw quarkus:dev -Dquarkus.http.port=9001
