Getting maven project version and artifact ID from pom while running in Eclipse

Question

I was looking up how to get the application name(artifact id) and version from maven pom or manifest when I came across this question Get Maven artifact version at runtime.<

Answer 1

Create a property file

src/main/resources/project.properties

with the below content

version=${project.version}
artifactId=${project.artifactId}

Now turn on maven resource filtering

  <resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
  </resource>

so that this file is processed into

target/classes/project.properties

with some content similar to this

version=1.5
artifactId=my-artifact

Now you can read this property file to get what you want and this should work every time.

final Properties properties = new Properties();
properties.load(this.getClassLoader().getResourceAsStream("project.properties"));
System.out.println(properties.getProperty("version"));
System.out.println(properties.getProperty("artifactId"));

Answer 2

An easy solution with maven 4 is now to add a VersionUtil static method in your package:

package my.domain.package;
public class VersionUtil {
  public static String getApplicationVersion(){
    String version = VersionUtil.class.getPackage().getImplementationVersion();
    return (version == null)? "unable to reach": version;
  }
}

The thing is you need this ´mave-war-plugin´ in the project's pom, saying you want to add addDefaultImplementationEntries:

<build>
    <finalName>${project.artifactId}</finalName>
    <plugins>
     ...
      <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.2.2</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
                <archive>
                    <manifest>
                        <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    ...

Then call the VersionUtil.getApplicationVersion() from some place in your code.
