maven aspectj编织NullPointerException

我有一个使用MyEclipse制作的Spring MVC应用程序，它包含生成的源以及我自己的源，以及我在生成的类上定义的方面。在MyEclipse中编译好的所有东西，但我现在想切换到Maven，以便使用持续集成服务器。maven aspectj编织NullPointerException

我一直在摆弄pom.xml很长一段时间了，我打了一道墙，我似乎无法绕过。当Maven到达织造方面的那一刻，我得到下面的异常（只是第几行为了简洁）：

[INFO] [aspectj:compile {execution: default}]

我的pom.xml太长，它粘贴在这里，但构建的部分是作为如下（让我知道，如果你想看到的一些相关性）：

任何人看到任何错误或遗漏可能会导致异常？仅供参考，我的aspectj依赖项（aspectjrt，aspectjtools和aspectjweaver）的版本是1.8.7。

这有帮助吗？ http://stackoverflow.com/questions/11044213/internal-compiler-error-in-eclipse-npe –

谢谢，但不是真的。编译发生在持续集成服务器（Bamboo）上，不在Eclipse内部，因此这些步骤不适用。 – timber

您应该将解决方案转移到下面的答案。 –

我似乎发现了这个问题。在pom.xml中，我在aspectj-maven-plugin定义之外，对pj文件的dependencies部分中的所有其他依赖项列出了aspectjtools的依赖项。相反，我将其移入插件中;另外，我将aspectj库的版本更改为1.8.9，因为它看起来像1.8.7展现了一个类似于我发现的bug。之后，一切都奏效了。所以这里是我为aspectj-maven插件修改的定义以供参考：

 <plugin> 
      <groupId>org.codehaus.mojo</groupId> 
      <artifactId>aspectj-maven-plugin</artifactId> 
      <version>1.8</version> 
      <dependencies> <!-- The change that fixed it starts here... --> 
       <dependency> 
        <groupId>org.aspectj</groupId> 
        <artifactId>aspectjtools</artifactId> 
        <version>1.8.9</version> 
       </dependency> 
      </dependencies> <!-- ...and ends here. --> 
      <configuration> 
       <showWeaveInfo>true</showWeaveInfo> 
       <source>1.6</source> 
       <target>1.6</target> 
       <Xlint>ignore</Xlint> 
       <complianceLevel>1.6</complianceLevel> 
       <encoding>UTF-8</encoding> 
       <verbose>true</verbose> 
       <aspectLibraries> 
        <aspectLibrary> 
         <groupId>org.springframework</groupId> 
         <artifactId>spring-aspects</artifactId> 
        </aspectLibrary> 
       </aspectLibraries> 
      </configuration> 
     </plugin>
