The problem is heroku currently using Java 8: Heroku Java versions
The indicator is this line:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project NCKHSV: Fatal error compiling: invalid flag: --release -> [Help 1]
I've encountered this problem when building maven application with target is Java 11 but running JDK is Java 8. I can't help with heroku since I haven't used it yet

At heroku you could really use the configurations in your pom.xml below,
please look carefully. :)
please check maven-plugin mentioned in pom.xml under <project>
I have something like this below.
...
<packaging>maven-plugin</packaging>
</project>
Futher more please check this plugin you could replace the below plugin code and modify as per your need. It can be added under build->plugins->THIS_PLUGIN
<plugin>

I hope, it helps!

Changing a 1.8 Maven Project to compile to 1.16 produces "invalid target release 1.16"

I've been searching a solution for hours, couldn't even find 1 post about maven compilation to 1.16
I recently decided to one of my projects from java 8 to 16, so I installed 16 JDK and changed my build section(in pom.xml) accordingly:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<source>1.16</source> //used to be 1.8
<target>1.16</target> //used to be 1.8
<compilerArgs>
<arg>-parameters</arg>
</compilerArgs>
</configuration>
</plugin>
</plugins>
</build>
But I get the following error when I try to install:

It's not 1.16, it's 16.
You don't have to configure the maven-compiler-plugin.
You can use the new release option.
<properties>
<maven.compiler.release>16</maven.compiler.release>
</properties>

I ran into a similar issue despite the fact that my settings were
<source>16</source> //used to be 8
<target>16</target> //used to be 8
The real insight came up when I ran
mvn --version
as this one pointed out I was running a current maven with JDK 11.
The solution was to change JAVA_HOME to point to my JDK 16 installation before running maven.

what do i need to add to my pom.xml ?

Ensure that you have system.properties file in the root directory of your repository with the following contents:
java.runtime.version=10
For more info see the Heroku documentation on Java versions

The -release argument is supported only since Java9 (https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html). Make sure your maven installation is using at least Java9.

Try using version 3.8.0 instead of 3.7.0. Also make sure your JAVA_HOME is set to your Java 8 installation. See this link

There's another option instead of adding the properties file in the repo location.
You can add this code in POM.xml:
<properties>
<java.version>1.8.0_171</java.version>
</properties>

Remove <release>10</release> from pom.xml and add system.properties in resources with content java.runtime.version=10. It should work with jdk 10. Or you can change the JDK as per your need.

Maven package error: No compiler is provided in this environment

I am new to Maven and I am trying to create a JAR out of a HelloWorld program.
I have done the classpath setting:
This is the pom.xml file:

JAVA_HOME is already set as C:\Program Files\Java\jdk1.8.0_121\bin in classpath. Please suggest how to resolve this issue.

Your JAVA_HOME is set to a JRE not to a JDK. The JRE does not include the Java Compiler, so set JAVA_HOME to a JDK and it should work

Also you can goto your project properties-> Libraries-> add Library -> JRE system Library -> Alternate JRE -> Add.
and then you choose your JDK path from your system and apply.
Make sure to remove JRE From project library.
In my case, this works well.

You need to tell java what class to run. Depending on the maven plugin you use the ways might be different. This link shows how it can be done with the help of the maven-assembly-plugin https://stackoverflow.com/a/45902851/6825678

Does your pom.xml set the Java Compiler version?
Some (all?) versions of maven-compiler assume the Java 1.4 compiler... which of course causes issues since Annotations were new in Java 1.5.
You can force it to Java 7 by including a plugin block for maven-compiler-version in your project's pom.xml and set its source and target properties... something like this:
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
[...]
</build>
[...]
</project>
