I couldn't find a way to create a Java 11 project directly, so I'll create a Java 8 project first. After creating, change to Java 11 settings.
OS:Windows 10 Pro 64bit Editor:Visual Studio Code 1.42.1 JDK:AdoptOpenJDK 11.0.6+10 x64 Apache Maven:v3.6.3
I think that you can also enter the command of Visual Studio Code, but this time I will create it by entering the command at the command prompt. Open a command prompt and move to the folder where you want to create the template. This time, create it in "D: \ JAVA \ Project".
mvn archetype:generate -DinteractiveMode=false -DarchetypeGroupId=pl.org.miki -DarchetypeArtifactId=java8-quickstart-archetype -DgroupId=com.example -DartifactId=hello -Dversion=1.0-SNAPSHOT -Dpackage=com.example -Dpackaging=jar
Line breaks for readability.
mvn archetype:generate
 -DinteractiveMode=false
 -DarchetypeGroupId=pl.org.miki
 -DarchetypeArtifactId=java8-quickstart-archetype
 -DgroupId=com.example
 -DartifactId=hello
 -Dversion=1.0-SNAPSHOT
 -Dpackage=com.example
 -Dpackaging=jar
The places to be specified arbitrarily are as follows. -DgroupId It will be the group ID. It is for identifying the creator, company, organization, etc.
-DartifactId It will be the artifact ID. I think it can be called the project name.
-Dversion You can specify the version. Unless you are particular about it, I think "1.0-SNAPSHOT" is fine.
-Dpackage The basics are the same as "-DgroupId".

Change java.version to 11.
Change before
<java.version>1.7</java.version>
After change
<java.version>11</java.version>
I like war for packaging, so change it to war.
Change before
<packaging>jar</packaging>
After change
<packaging>war</packaging>
This is the modified pom.xml.

This completes the template creation.
