Maven Error When Executed Using Eclipse - No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

One may see following error for the first time when maven project is tried to be run using POM -

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project Json: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

Problems is about setting JRE version in eclipse/setting javac in POM.

To fix the eclipse to run Maven test -

1. Go to Installed JREs in following way through Eclipse Menu options
Menu ->Windows->Preferences->Installed JREs.

2. Select/Add Installed JRE

Another Approach -
To fix the POM - Set Maven-compiler-plugin

Reference -
http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html

1. <build>
2. <plugins>
3. <plugin>
4. <groupId>org.apache.maven.plugins</groupId>
5. <artifactId>maven-compiler-plugin</artifactId>
6. <version>3.5.1</version>
7. <configuration>
8. <verbose>true</verbose>
9. <fork>true</fork>
10. <executable><!-- path-to-javac --></executable>
11. <compilerVersion>1.3</compilerVersion>
12. </configuration>
13. </plugin>
14. </plugins>
15. </build>

Some times, in-appropriate testng version causes issue.

For example I got following issue with 6.9.13.6 -

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project Json: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test failed: The forked VM terminated without saying properly goodbye. VM crash or System.exit called ? -> [Help 1]

Solution - 

TestNG version 6.9.9 worked well for me.
