JDK and Maven issue

When a maven project fails to build, you first need to check if the mvn package -DskipTests can work directly in cmd line or not. If yes, then it is most likely the JDK version or maven version issue.

Intellij ships with a bundled maven which may be too old. You can check its version as below. You can choose maven wrapper which is a repo specific maven script. mvnw is similar to gradlew. You can set it up by mvn wrapper:wrapper. The generated property file is like below.

$ cat .mvn/wrapper/maven-wrapper.properties
wrapperVersion=3.3.2
distributionType=only-script
distributionUrl=https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/3.9.10/apache-maven-3.9.10-bin.zip

It also generates a shell script mvnw that basically does the following thing.

1. Check if $HOME/.m2/wrapper/dists/apache-maven-<version>-bin exits or not.
2. If exists, then use it to run maven command.
3. If not, then download it first.
