使用带有eclipse和m2e的maven-jaxb-plugin时,ErrorListener丢失

Question

我已经为插件设置了一个项目" org.jvnet.jaxb2.maven2:maven-jaxb2-plugin".它可以工作,但我不喜欢Eclipse编辑器中为"pom.xml"显示的错误消息.消息指出:

Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.13.1:generate failed: A required class was missing while executing org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.13.1:generate: com/sun/xml/bind/api/ErrorListener

pom和整个项目被标记为错误.

这是我的pom.xml:

我的" mvn validate"命令没有说明任何错误,并且声明的ErrorListener提供了工件" com.sun.xml.bind:jaxb-core".正如已经说过的,当运行项目来生成源代码时,它工作正常.有没有人运行这个插件并可以共享他的pom.xml？

Answer 1

将插件更新到版本0.13.3可修复此问题.

Answer 2

我通过从Eclipse首选项(Java>已安装的JRE)中删除任何JRE并仅将选定的JDK保留在那里来解决此问题.即使未选择JRE,它们仍会导致问题,必须将其删除.我能够将JRE留在我的系统上.这篇文章很有帮助:http://diggingthroughcode.blogspot.ca/2016/05/trouble-with-maven-jaxb2-plugin-and.html

[更新]另一位同事刚刚遇到这个,对他来说,似乎关键因素是Java被用来运行Eclipse.它也不会使用JAVA_HOME的配置,而是第一个可用的Java运行时.他从他的系统中删除了所有的jres并且只留下了一个jdk并解决了这个问题.我认为关键因素是eclipse是以jre还是jdk运行.当我解决了这个问题时,我确实从我的系统中删除了一个jre,这可能是eclipse一直在使用的.有了这个jre,它变成了jdk,即使我有其他jres可用.如果你不想从系统中删除jres,你可以指定java运行时eclipse应该使用什么(如何使用不同的java版本运行eclipse？).如果没有指定任何内容,eclipse将确定要使用的java运行时(找出运行的JVM Eclipse).

Answer 3

此问题是由在JRE而非JDK上运行的Eclipse引起的。

编辑您的eclipse.ini并指向合适的JDK-例如

-vm C:/Program Files (x86)/Java/jdk1.7.0_55/bin/javaw.exe
