Jenkins Maven plugin error "maven-release-plugin:jar:3.8.2 is missing"

I am new hear but i have gone through numerous posts and websites and finally am posting as I am not sure what else to do. Please excuse if the formatting or the way i have posted is not correct. 1st time here as i said.
If i directly run mvn clean package deploy the build is successful.
But fails when i run the build from jenkins.
I am getting the following error in Jenkins when trying to run a build

Ok finally found the problem.
The maven-release-version was incorrect. Already knew as pointed by #khmarbaise but WHICH ONE?
After a day of struggling I realized it was the pom.xml on GIT that was being pulled.
This one had the wrong version 3.8.2
So I corrected the POM.XML on GIT and corrected the release version.
FINALLY a success!!

How do I deploy the JDK 15 app in Heroku?

I have a system.properties that contain java.runtime.version=15 in my resource.
You placed it in /src/main/resources.
You are supposed to place it in the root folder / of your git repo.
In my case the content of my system.properties is java.runtime.version=10.0.2 and is placed in the root directory of my git repo.
In the build.log immediately after Java app detected it should install the specified Java version:

Java 11 without modularity: package does not exist while it is added as maven dependency

I have three very simple applilcations. One is COMMON which I will center security configs, other with ZUUL feature and the third is a EUREKA SERVER. Both are Spring Boot and Java 11. Although I am using Java 11 I am not reling on modularity (as far as I know it will not make sense use modularity feature with Spring Boot).
When I run all three in Eclipse I successfully can run the server, common and zuul in that sequence. When I try to maven build I get the error mentioned in subject.
The immediate explanation would be "you don't have common in zuul classpath". Well, as far as I check I do have common in zuul classpath. I am wondering if there is any extra config because I am using Java 11 but not using modularaty.
By saying I am using Java 11 but not modularity I mean, I have Java 11 but I don't have module-info.java at all in any of the three projects.
Checking in .m2 folder and unzip the common.jar I do see the class complained.

That's because the common project is a Spring Boot Application (I see the BOOT-INF folder inside the generated jar).
From Use a Spring Boot Application as a Dependency documentation:
The executable archive cannot be used as a dependency as the
executable jar format packages application classes in BOOT-INF/classes.
This means that they cannot be found when the executable jar is used
as a dependency.
To produce the two artifacts, one that can be used as a dependency and
one that is executable, a classifier must be specified. This
classifier is applied to the name of the executable archive, leaving
the default archive for use as a dependency.
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>exec</classifier>
</configuration>
</plugin>
</plugins>
</build>
Here is an example:
The first jar is build as dependency-able, the second one is Spring Boot executable.

That Eclipse is able to resolve Eclipse projects of the currently open workspace as Maven dependencies into other projects is a specialty of Eclipse.
If you execute Maven on command-line or from within Eclipse you leave the sphere of Eclipse and use plain Maven. Plain Maven (even the in Eclipse integrated Maven) does not know about Eclipse projects, it only knows the artifacts available in your local and the configured remote repositories.
Therefore the correct approach in your case is to first execute mvn install on your common project. This installs common into your local repo and makes it available to Maven.
Afterwards you can execute mvn clean install on your zuul project.

Spring Boot application build with Maven encounters Java Version Issue

I was trying to build an application using maven build.It was returning this build failure even though I have placed my pom.xml file is in-place.
I have configure my pom with out any issue.But I can see that there is some error returning related to schema.But don't have much information on that

According to your logs:
Fatal error compiling: invalid target release: 1.8.0_73
You might be using an inferior JDK version (1.7 for example) to compile your project to a higher target version (1.8.0_73 in your case).
Try installing JDK 1.8 and make your JAVA_HOME environment variable point to it.
Generally you should make sure the source JDK and target JDK are matching between your pom.xml file and your JAVA_HOME environment variable.

You can try maven compiler plugin
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>

Remove the duplicate dependency added
<artifactId>spring-boot-starter-test</artifactId>
And
Try pointing to JDK 1.8 in project build path and make your JAVA_HOME environment to this

In general the minor release number (for java) is not configured in pom.xml. Only major release number will be require.
Try to change 1.8.0_73 to 1.8.
To understand the java version system please visit this link.

Looking in your maven output, it is clear that you have a duplicate dependency declaration. Moreover, it is clear that the duplicate dependency is the org.springframework.boot:spring-boot-starter-test.
What is the process of solving the issue and removing this WARNING:
Look VERY carefully your pom.xml. You probably have declared the dependency twice.
An other cause of this warning might be that a dependency is declared twice, but with different versions. The solution, again, is to delete the dependency for one of them.
Command mvn dependency:tree -Dverbose might be useful.
Finally, after writing the above process, I looked in the pom.xml file you posted in your question and found that you have declared the following dependency twice (line:54 and line:65).
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
As far as I am concerned, this library is used for testing purposes only. If this is true, depending on your requirements, you should keep only the dependency in line 54 and the warning will be removed.

Is there anything i need to add to pom.xml?

It's all in the log:
No response received after 60000
Maven is trying to download dependencies for the plugins that you are using, and it's failing because of a timeout. Check your network connection and ensure you can access the Maven central repository (http://repo.maven.apache.org/maven2).
