我是maven的新人，我根本没有时间研究它。 对于我的一般性问题，我很抱歉。
我正在使用MVC JSF JPA编写我的应用程序，依此类推。我在测试方面遇到了问题，我看到了一些关于嘲弄的事情，但我觉得这对团队项目很有好处，我不知道项目的所有内容。
所以我正在寻找一些有用的东西作为＆＃34;真实案例＆＃34;测试......我找到了arquillian！使用arquillian的更快更简单的方法是使用maven。所以我把我的项目转换成了一个maven项目。
我在Netbeans中使用嵌入式版本。干净后，当我尝试运行我的应用程序时，它会返回

答案 0 :(得分：1)
阅读maven输出：
要查看错误的完整堆栈跟踪，请使用-e开关重新运行Maven。 使用-X开关重新运行Maven以启用完整的调试日志记录。
这意味着您必须以这种方式执行maven才能显示异常：
mvn -X
要在Netbeans中执行此操作，请打开项目属性，选择“操作”，然后选择要执行的操作。将-X添加到执行目标。
再次重新运行测试，您将在输出控制台中获得真正的异常。
这看起来很奇怪，可能会导致问题：
<dependency>
<groupId>org.jboss.shrinkwrap.resolver</groupId>
<artifactId>shrinkwrap-resolver-bom</artifactId>
<version>2.0.0-alpha-1</version>
<scope>test</scope>
<type>pom</type>
</dependency>
你在alpha版本中使用旧的收缩膜旋转变压器！ 删除此依赖项，并将其用作普通依赖项。该版本已在arquillian-bom中定义。
<dependency>
<groupId>org.jboss.shrinkwrap.resolver</groupId>
<artifactId>shrinkwrap-resolver-impl-maven</artifactId>
<scope>test</scope>
</dependency>
答案 1 :(得分：-2)
右键单击您的项目，选择run as - ＆gt; maven build ... 在目标中写道：
mvn -X clean install
在你的pom.xml中发现了问题
$ {project.build.directory} /认可
$ {project.build.directory}是您使用但尚未定义的变量
你可以这样做
<properties>
<project.build.directory>your build directory here</project.build.directory>
</properties>
