Very simple maven plugin to create java constant class from maven properties.

You can add a constant just by property definition:

<properties>
    <constant.my.actifact>${project.artifactId}-${project.version}</constant.my.actifact>
</properties>

define the MY_ARTIFACT constant with the given value.

The constants NAME, FULL_NAME, VERSION, BUILD are defined by default with the values ${project.artifactId}, ${project.artifactId}, ${project.artifactId}, ${session.request.startTime}.

You can redefine there's using properties:

<properties>
    <constant.version>${project.artifactId}-${project.version}</constant.version>
</properties>

The project.artifactId is converted to class name by capitalizing all words and removing dots. The project.groupId is used for package name. The ${maven.build.timestamp.format} is used, if defined, for the BUILD constant.

Usage:

        <plugin>
            <groupId>org.sekaijin</groupId>
            <artifactId>constants-maven-plugin</artifactId>
            <version>1.0.0-SNAPSHOT</version>
            <executions>
            <execution>
                <id>constants</id>
                <goals>
                <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

The result is :

    package com.sap.conn;

    public class SapJco3
    {
        public static final String FULL_NAME ="SAP :: JCO :: 3";
        public static final String NAME ="sapjco3";
        public static final String BUILD ="2020-12-05 17:12:20 CET";
        public static final String VERSION ="sapjco3-3.0.0";
    } //class
