Unsupported Major.minor version 51.0 the JDK does not conform to the JDK versions referenced by MAVEN when configuring/running MAVEN Engineering

During the configuration of the MAVEN project, the following error was encountered during the deployment to the Tomcat server to run:

1 " "

The reason for the error is that the JDK version referenced by Maven is inconsistent with the version referenced by Tomcat, and the solution is as follows:

1. Modify the JDK version of MAVEN to 1.7:

A) in Maven's setting file, add

Add the following profile elements under the Profiles element in the Setting.xml file <profile>    <id>jdk17</id>    < Activation>        <activeByDefault>true</activeByDefault>        <jdk>1.7 </jdk>    </activation>    <properties>        <maven.compiler.source>1.7 </maven.compiler.source>        <maven.compiler.target>1.7</maven.compiler.target>        <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>    </ Properties>    </profile>

b) Add the following build element to the project's Pom,xml file

<build>    <plugins>        <plugin>            <groupid>org.apache.maven.plugins</groupid >            <artifactId>maven-compiler-plugin</artifactId>            <configuration>                <source >1.7</source>                <target>1.7</target>            </configuration>        </plugin>    </plugins></build>

c) myeclipse->windows->perference-> Find maven-> Modify JDK version (optional)

2. Modify the JDK version of Tomcat:

Myeclipse->window->servers->tomcat->tomcat7.x->jdk-> to 1.7 (same as MAVEN)
