Maven 在 Jenkins 中抛出 "Cannot find symbol"

Question

我正在为 Jenkins 和 Sonarqube 创建一个本地实例。 创建项目并进行配置后，我单击“立即构建”。 在控制台输出中，我可以看到 Maven 开始下载所需的元数据，一旦完成，它就会抛出 编译错误“找不到符号”项目。

Maven 也安装在我的机器上，我尝试从 GIT 下载项目并通过命令提示符运行 maven，它成功构建。只有当我通过 Jenkins 构建时，我才会遇到这个问题。有人可以帮我解决这个问题吗。

请注明Java的编译版本。这就是您遇到此问题的原因 - UnsupportedClassVersionError 尝试在您的 pom.xml 中添加类似的内容

<build>
    <plugins>
        <!-- START Of Plugins -->
        <!-- MAVEN COMPILER PLUGIN -->
        <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>
        <!-- END Of Plugins -->
    </plugins>
</build>

这里我用的是1.7的jdk。但如果需要，您可以更改它。

请告诉我它是否有效...
