Thanks In Advance...

it looks like the Maven Compiler plugin is using Java 5 (it should be using Java 6 by default), hence you get the build error diamond operator is not supported in -source 1.5
Heroku supports various Java version (see Supported Java versions), you should just be able to set the target version in your POM file
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>

The diamond operator – introduced in Java 1.7 – adds type inference and reduces the verbosity in the assignments.
Problem in your source code try to re-write it.
I had similar issu and my now looks like this
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Kindly help me to fix the issue.

Assuming you have a Main.java in src/test/java
Add this in your pom.xml
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<configuration>
<classpathScope>test</classpathScope>
<mainClass>Main</mainClass>
</configuration>
<executions>
<execution>
<id>run-selenium</id>
<phase>integration-test</phase>
<goals><goal>java</goal></goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
and run it via :
mvn clean install or mvn exec:java

Maven runs JUnit tests in Eclipse but compilation fails from the command line

I have created a very simple project in Eclipse to run a very simple JUnit test. These tests work fine when tests are executed from within Eclipse, but the code does not compile when run via maven command line.
The command I am using to run maven is simply 'maven test'. The following is the maven output:

import org.junit.Test;
public class ReferenceTestClient

#Test
public void testOne()

System.out.println("simple test");
}
}
That's it... no other files in the project. Maven tests run successfully from within Eclipse, but the code doesn't even compile from within Maven.
A valid pom.xml file, or other modifications to this simple project, is appreciated.

You have your file in src/main/java/ directory but the scope for the JUnit dependency is test. This means maven will not take it into account when compiling non-test code. Please put your file in src/test/java.

Test scope means that junit is only available in src/test/java

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>

The error happens only after I add the changes-maven-plugin regardless of whether there is anything in src/changes/ or not. Up until now, I wasn't able to figure out what exactly the problem is. Can someone explain what I'm doing wrong here?

I think you want to use the maven-changes-plugin instead.
