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

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.

JAVA_HOME="/C/Program Files/Java/jdk-11.0.9"
MVN=$(pwd)/mvnw

$MVN clean package -Dmaven.test.skip=true

create system.properties file and Add java.runtime.version=11

What could be the problem? How to solve it? please i need help :(

change
<java.version>11</java.version>
to
<java.runtime.version>11</java.runtime.version>

I could solve it by downgrading everything to version 1.8, including my paths

hamcrest-core: jar:1.4-atlassian-1 could not be resolved on MVN clean install on Spring Boot project

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.

For me, the problem was that maven was using a different version of Java than the project.
After I changed it so that both maven and project are using the same versions of Java, everything worked fine.
The discrepancy in my case was that the project was on java 1.8 and maven was using java 1.7.
I changed the maven version of java directly since I needed to have an older version of Java set in Java Home. For that, I referred to this topic: How to set specific java version to Maven
I hope that this helps.

In my case I did this:
In pom.xml added the following lines:
<properties>
<java.version>1.8</java.version>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
Go to the properties of the proyect -> Java Build Path -> Libraries
Checked that the "JRE System Library[]" was using "JavaSE-1.8 (jre1.8.0_221) as JRE.
Selected "JRE System Library" -> Click on "Edit..."
Ticked the option "Alternate JRE:" and selected "jdk1.8.0_221".
Saved everything, executed "Maven Clean" in the project and Installed Maven in the project.
After Eclipse downloaded the repositories of Maven, the build was successful.
