我正在尝试按照此来源的步骤创建一个OpenIMAJ项目： http://www.openimaj.org/tutorial/getting-started-with-openimaj-using-maven.html
我跑了命令：
mvn -DarchetypeCatalog=http://maven.openimaj.org/archetype-catalog.xml archetype:generate
并选择openimaj-quickstart-archetype，groupID，artifactID，左版本为1.0-SNAPSHOT，这样包，并且能够成功创建一个新项目。
由archetype创建的默认项目包含一个小的“hello world”应用程序，我尝试通过以下方式编译和汇编：
cd trial2
mvn assembly:assembly
但构建失败，我收到以下错误：
F:\OpenImaj\trial2>mvn assembly:assembly

大多数解决方案建议我检查我的java_home变量。设置正确：
F:\OpenImaj\trial2>echo %java_home%
C:\Program Files\Java\jdk1.7.0_55
另外，我的java版本是：1.8.0_31
和maven版本：
F:\OpenImaj\trial2>mvn -version
Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T17:27:37+05:30)

这种构建失败可能是什么问题？
非常感谢帮助.. 在此先感谢
编辑： 我正在尝试生成jar-with-dependencies.xml文件，这对我不起作用。
