不支持的major.minor版本52.0 - Maven Error JAVA

我在做

mvn安装

我得到错误：

[错误]无法执行目标org.alfresco.maven.plugin：alfresco-maven-plugin：2.1.0：项目componentX-share上的set-version（default-set-version）：执行default-set-version of goal org.alfresco.maven.plugin：alfresco-maven-plugin：2.1.0：set-version failed：无法在插件'org.alfresco.maven.plugin中加载mojo'set-version'：alfresco-maven-plugin ：2.1.0'由于API不兼容：org.codehaus.plexus.component.repository.exception.ComponentLookupException：org / alfresco / maven / plugin / VersionMojo：不支持的major.minor版本52.0

但是我已经看过java的版本是否相同，而且它是正确的 .

我认为一切都是正确的 . 还有我的pom.xml：

我已经尝试将行添加到pom.xml中，如：

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>

我在“stackoverflow”的其他解决方案中看到过，但我无法解决问题 . 我不想升级Java的版本（如果它是解决方案）我想在Java 7中运行 . 任何想法？

如果解决方案仅针对Java 8进行升级，请告诉我 .

谢谢 .
