Maven 马文抛出；找不到符号“；在詹金斯

我正在为Jenkins和Sonarqube创建一个本地实例。 创建项目并配置项目后，我单击了“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，一旦下载完成，就会抛出编译错误“无法找到项目中每个文件的符号”

Maven也安装在我的机器上，我尝试从GIT下载该项目，并通过它成功构建的命令提示符运行Maven。只有通过Jenkins进行构建，我才会遇到这个问题。有人能帮我解决这个问题吗

请指定Java的编译版本。这就是您面临此问题的原因-UnsupportedClassVersionError 尝试在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>

org.apache.maven.plugins
maven编译器插件
3.3
1.7
1.7

这里我使用了1.7JDK。但如果需要，你可以改变

请告知它是否有效…

它指的是哪个符号？它不仅仅是一个符号吗？你必须更具体地说明你所说的错误<代码>找不到符号发生在类路径上出现错误时，因此maven找不到导致此错误的任何类及其方法。看看是否正确安装了maven。查看是否在jenkins服务器上安装了java jdk而不是jre。查看是否设置了正确的环境变量。看看你的项目是否没有使用任何本地库（一个只有你机器上才有的库）。我已经删除了maven实例。下载并安装了一个新的副本为我做到了这一点。但是现在在sonar中再次“无法执行goal org.codehaus.mojo:sonar maven插件：2.6:sonar（默认cli）”，这些是一个非常普遍的例外-你应该提供整个错误，因为插件失败的原因有很多。这就是我使用JDK1.6升级到1.7的原因。除此之外，我还找到了另一个解决方案。如果Jenkins、maven和Sonar安装在同一个系统中，您可以提到“Sonar:Sonar”，它与jdk1.6本身一起工作。报告可以在声纳中查看。
