I solved this problem by adding a new file system.properties and the content added to the file is java.runtime.version=11 (For me I am using JDK 11).
java.runtime.version=11

I would try focusing on why maven complains about invalid release 11 (Fatal error compiling: invalid target release: 11).
As seen in your pom.xml config you clearly intend to use version 15, so I would suggest to investigate why there is a problem with version 11.
Check $JAVA_HOME environment variable, system.properties file, etc.
Also try debug route suggested in official docs or a Q&A on a similar topic.

You must use the specific version of Java supported by Heroku. The following versions supported are:
Java 7 - 1.7.0_292
Java 8 - 1.8.0_282
Java 11 - 11.0.10
Java 13 - 13.0.6
Java 15 - 15.0.2
Set a java.runtime.version property of the system.properties file, create a system.properties file if one does not already exist.
java.runtime.version = SUPPORTED_VERSION
Read more in heroku-java-support

This is what I have experienced today.
I have been using jdk 1.8, and then have to install jdk 1.11.
But, after running mvnw through my shell script file dep.sh, it failed to build jar.
#!/bin/bash
MVN=$(pwd)/mvnw
echo "[1/2] Building app.jar ..."
$MVN clean package -Dmaven.test.skip=true
dep.sh calls mvnw script file with goal clan package

When I installed jdk 1.8, JAVA_HOME was set to /my/jdk/1.8/dir, which is used for bundling jar.
I set JAVA_HOME to /my/jdk/1.111/dir in dep.sh, it works without error.

Any idea why am getting this error related to hamcrest jar? I added the same version of the jar in .m2/repo/... but I still get the same error. Any idea which dependency in this POM is using it internally? Do I have to change any version?
Command used to build
mvn clean install
If I run this project as Spring Boot app then the service is up but what I need is a jar out of this to host in a cloud.

This was the issue with my local repository. I had to point to a new repo location under .m2 in settings.xml.

You need to actually check whether the version of identity jar is compatible with java version. If you are sure than you can try the project without using maven configuration. If all works well than try clearing maven .m2 folder as many a times, maven keeps the list of jars in cache and doesn't loads the newer jar.

Process finished with exit code 1

Your problem is here
<log4j2.version>${log4j2.version}</log4j2.version>
Indeed your error means that "${log4j2.version}" is not a valid version.
You are supposed to set explicitly a version of log4j2 instead of "${log4j2.version}" for example you could use 2.7 if you want to use the latest version (which is also the version on which org.apache.struts:struts2-core:2.5.5 relies), see the list of existing versions here.
So try this
<log4j2.version>2.7</log4j2.version>

Problem is with < log4j2.version > property.
Property in a POM file is expected to be a constant value which can be replaced when the property is referred. But in your case you'r pointing to the same property which is an error.
if you want to include a specific version then provide it in < log4j2.version> tag like:
< log4j2.version>1.2.17< /log4j2.version>
or you can use
< log4j2.version>LATEST< /log4j2.version>,
'LATEST' keyword can automatically pick the latest version of the dependency from maven repository
