摘要:
运行“mvn war:war”失败，并显示以下错误:
“无法解析以下工件:org.openid4java:openid4java:jar:0.9.6”。
我认为我是Maven新手，但我发现其他人已经从Maven中心发布到openid4java网站，声明jars are missing为openid4java。
详细信息:
我正在尝试通过运行最新版本的openid4java(0.9.6.662)中包含的Simple-OpenID示例应用程序来快速掌握openid4java。
根据自述文件“此演示需要使用Apache Maven2进行构建”。自述文件还指出“mvn war:war任务应创建一个战争文件，可以通过复制该战争文件进行部署”。
到目前为止，我对Ant和Mavent Ant Tasks的了解不多，但我想今天我要硬着头皮安装Maven 3.0.3。我已按照安装说明进行操作，现在可以成功运行“mvn --version”
当我运行“mvn war:war”时，确实确实有许多文件下载到我的本地存储库中，但是最终构建失败并显示以下摘录的消息:

我在这里做错了吗，还是Maven存储库中实际上缺少了jar？
最佳答案
通过将<type>pom</type>添加到pom.xml，我能够解决此问题。我在this thread的OpenID4Java google组中找到了答案。
这是Google群组中的线程所说的:
我的意思是你应该加上
“pom”到依赖
您的openid4java部分
pom.xml:
<dependency>
<groupId>org.openid4java</groupId>
<artifactId>openid4java-consumer</artifactId>
<!--artifactId>openid4java-server</artifactId-->
<!--artifactId>openid4java-infocard</artifactId-->
<!--artifactId>openid4java-xri</artifactId-->
<!--artifactId>openid4java</artifactId-->
<!--artifactId>openid4java-full</artifactId-->
<version>0.9.6</version>
<type>pom</type> <-----------------------This line can not be omitted.
</dependency>
openid4java-consumer / openid4java-server / ....的类型都是“pom”而不是“jar”。 jar文件位于openid4java-nodeps中，取决于openid4java-consumer / openid4java-server ...
