structure of my project

Answer 1

The project that you are trying to release must have a SNAPSHOT version. It should look like this:

<version>X.X.X-SNAPSHOT</version>

Answer 2

there not sure if this will help because I didn't see the whole error but I hope it does 1/get rid of

<properties>
    <java.version>1.8</java.version>
</properties>

and add this to the root
       

   <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-release-plugin</artifactId>
            <configuration>
                <goals>install</goals>
            </configuration>
        </plugin>
 <scm>
    <developerConnection>scm:git:${git_url}</developerConnection>
  <tag>HEAD</tag>
</scm>

2/ do a mvn clean 
3/ do mvn release:prepare
4/ do mvn release: perform
