Question

好的我只是用我发现的新线索重新构建我的问题，因为我没有得到前一个答案。所以！詹金斯正在使用错误的公共资源。我正在运行Jenkins的1.598版本。在“关于”部分，我可以看到它使用的是commons-io版本2.4。

当我在Jenkins上运行我的maven项目时，项目构建是成功的，但是当Jenkins开始运行PMD或checkstyle分析时，我有以下错误：

java.lang.NoSuchMethodError: org.apache.commons.io.IOUtils.lineIterator(Ljava/io/InputStream;Ljava/nio/charset/Charset;)Lorg/apache/commons/io/LineIterator;

...

这个方法（lineIterator（Ljava / io / InputStream; Ljava / nio / charset / Charset;））存在于commons-io 2.4中，所以我的猜测是Jenkins正在使用另一个jar。

我在服务器上为commons-io运行了一个locate，结果如下：

正如你所看到的那样，有一些commons-io 1.4的出现，它不包含丢失的方法！所以它必须是詹金斯使用的那个。

在项目的日志中，我可以看到：

java -cp /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven-agent-1.6.jar:/usr/share/maven2/boot/classworlds.jar hudson.maven.agent.Main /usr/share/maven2/ /var/cache/jenkins/war/WEB-INF/lib/remoting-2.49.jar /var/lib/jenkins/plugins/maven-plugin/WEB-INF/lib/maven-interceptor-1.6.jar 56025

在locate：

/home/jenkins/.m2/repository/commons-io/commons-io/1.4/commons-io-1.4.jar
/usr/share/java/commons-io-1.4.jar
/usr/share/maven-repo/commons-io/commons-io/1.4/commons-io-1.4.jar

/var/lib/jenkins/.m2/repository/commons-io/commons-io/2.4/commons-io-2.4.jar

所以我猜问题就在这附近，但我不知道如何解决它！我不能只是从服务器中删除commons-io 1.4的出现，因为其他一些程序可能会使用它们。谢谢您的帮助，纪尧姆

Answer 1

我们找到了解决方案！这似乎是由服务器上使用的maven版本引起的（2.2）。我在Jenkins中将它升级到3.2.2，它现在完美无缺！

詹金斯使用了错误的公地 - io
