运行maven站点的奇怪问题（处理POM时遇到问题）

时间：2015-04-23 11:20:37

标签： java maven-3 maven-site-plugin

我试图运行mvn网站，但每次都会收到此错误消息。我试过谷歌搜索，但没有找到任何解决方案。我目前在使用git bash运行maven的Windows机器上。

[WARNING] Unable to create Maven project for org.crashub:crash.shell:pom:1.3.1 from repository.
org.apache.maven.project.InvalidProjectModelException: Some problems were encountered while processing the POMs:

我发现了这两个相关的问题：

https://jira.exoplatform.org/browse/CRASH-225

https://jira.codehaus.org/browse/MSHADE-185

所以原因似乎是在Maven Shade插件中：CRaSH POM似乎使用Shade插件然后有错误的，硬编码的systemPath。

根据http://www.crashub.org/：

  

CRaSH正式嵌入Spring Boot远程shell。

所以org.crashub：crash.shell：pom：1.3.1似乎与Spring Boot有关，但我不知道警告的意思是什么：“无法为[...]创建Maven项目“

修改

尝试将以下依赖项添加到您的POM：

<dependency>
    <groupId>com.sun</groupId>
    <artifactId>tools</artifactId>
    <version>1.8</version>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
    <optional>true</optional>
</dependency>
