不支持 Class 版本在 Maven build in Jenkins

[英]Unsupported Class Version during Maven build in Jenkins

原文 2014-09-03 23:47:42 2 2 java/ maven/ jenkins/ java-7/ jdk6

I've seen a few of these questions on here, but none of the solutions/tips seem to be pointing me in the right direction.我在这里看到了其中一些问题，但似乎没有一个解决方案/提示能为我指明正确的方向。 So I have 3 JDK's installed in the locations of "/opt/java/6", "/opt/java/7", and "/opt/java/8".所以我在“/opt/java/6”、“/opt/java/7”和“/opt/java/8”的位置安装了 3 个 JDK。 All of these are set in the global Jenkins configuration.所有这些都在全局 Jenkins 配置中设置。 Jenkins itself is run using Java 8 which is the system default JRE that I set manually through alternatives (I'm using CentOS 7). Jenkins 本身使用 Java 8 运行，这是我通过替代方法手动设置的系统默认 JRE（我使用的是 CentOS 7）。 I had a bunch of old projects that are built using maven and the maven compiler plugin which is set to source=1.6 target=1.6.我有一堆旧项目是使用 maven 和 maven 编译器插件构建的，该插件设置为 source=1.6 target=1.6。 Every time I try to execute a build with the Java 6 JDK I get每次我尝试使用 Java 6 JDK 执行构建时，我都会得到

This indicates that there's Java 7 interfering somewhere, but I'm not sure where.这表明有 Java 7 干扰某处，但我不确定在哪里。 The code is 1.6 compliant and most of the projects have no dependencies, so I'm not sure why this is happening.该代码符合 1.6 标准，并且大多数项目都没有依赖项，所以我不确定为什么会这样。 If I execute maven outside of Jenkins, the projects build just fine with JDK 6, so its leading me to think there's a misconfiguration in Jenkins somewhere, but I'm not sure where since everything seems to be as it should be.如果我在 Jenkins 之外执行 maven，则项目使用 JDK 6 构建得很好，所以它让我认为 Jenkins 某处存在错误配置，但我不确定在哪里，因为一切似乎都应该如此。 The paths to the JDKs are set properly in the global config and the projects themselves are set to use the specified JDK's. JDK 的路径在全局配置中正确设置，项目本身设置为使用指定的 JDK。 I apologize if its a duplicate question or something silly, but I've been trying to figure this out for days with no results.如果这是一个重复的问题或一些愚蠢的问题，我深表歉意，但我已经尝试了好几天都没有结果。 Everyone just says to check the paths and make sure there are no dependent artifacts built with a later JDK and I'm sure that this is not the problem.每个人都说要检查路径并确保没有使用更高版本的 JDK 构建的依赖工件，我确信这不是问题所在。

2 个解决方案

You have an old java version. 您有一个旧的Java版本。 For example in my case I´m compiling an old product so I have to keep the java deprecated version. 例如，在我的情况下，我正在编译一个旧产品，因此必须保留不推荐使用的Java版本。 So the solution was to download a newest jdk and configure the JAVA_HOME in the slave. 因此，解决方案是下载最新的jdk并在从属服务器中配置JAVA_HOME。 http://lmarccdk12.ptx.fr.sopra:14000/computer/ /configure in the section Advanced/JavaPath=/root/jdk1.7.0_79/bin/java (that´s the version I chose) http：//lmarccdk12.ptx.fr.sopra：14000 / computer / / configure（位于Advanced / JavaPath = / root / jdk1.7.0_79 / bin / java部分）中（这是我选择的版本）

You will see the following message in the slave launch log: [SSH] Starting slave process: cd "/root" && /root/jdk1.7.0_79/bin/java -jar slave.jar 您将在从属启动日志中看到以下消息：[SSH]正在启动从属进程：cd“ / root” && / /root/jdk1.7.0_79/bin/java -jar slave.jar

Your Jenkins job is of type "Maven project", and this job type has a limitation in that it cannot run a Maven build with a JDK version that is older than the Java version under which Jenkins is run.您的 Jenkins 作业类型为“Maven 项目”，此作业类型有一个限制，即它不能运行 Maven 构建，其 JDK 版本比运行 Jenkins 的 Java 版本旧。

Beginning with Jenkins 2.357 (released on June 28, 2022) and the forthcoming 2.361.1 LTS release, Jenkins requires Java 11 or newer.从 Jenkins 2.357（2022 年 6 月 28 日发布）和即将发布的 2.361.1 LTS 版本开始，Jenkins 需要 Java 11 或更新版本。 Therefore, you can no longer run Maven projects with JDKs 1.6, 1.7 and 1.8.因此，您不能再使用 JDK 1.6、1.7 和 1.8 运行 Maven 项目。 The minimum version is now Java 11.最低版本现在是 Java 11。

To resolve this, you may:要解决此问题，您可以：

Create a Freestyle project and use Invoke top-level Maven targets to invoke Maven, or create a Jenkins Pipeline project.创建一个 Freestyle 项目并使用Invoke 顶级 Maven 目标来调用 Maven，或者创建一个 Jenkins Pipeline 项目。 In both cases, using an older JDK will be possible.在这两种情况下，都可以使用较旧的 JDK。
Use JDK 11 but set source and target version to the older Java version.使用 JDK 11，但将源和目标版本设置为较旧的 Java 版本。 I haven't tried that though, and I believe this option may cause other trouble.不过我还没有尝试过，我相信这个选项可能会导致其他麻烦。
