openid4java的Maven“无法解决依赖关系”

Question

摘要：

运行"mvn war:war“时失败，错误包括：

“以下工件无法解析: org.openid4java:openid4java:jar:0.9.6”。

我认为这是因为我是一名Maven noob，但我看到其他人在openid4java网站上发布了罐子不见了，声明来自Maven中心的openid4java。

详细信息：

我正试图通过运行最新版本的openid4java (0.9.6.662)中包含的简单-OpenID示例应用程序来提高openid4java的速度。

根据自述文件，“这个演示需要apache Maven2来构建”。自述文件还声明“mvn war:war任务应该创建一个war文件，该文件可以通过复制war文件来部署”。

到目前为止，我一直在处理Ant和Mavent任务，但我想今天我会咬紧牙关，安装Maven 3.0.3。我遵循安装说明，现在可以成功地运行"mvn --version“。

当我运行"mvn war:war“时，确实会将许多文件下载到我的本地存储库中，但最终构建会失败，并会收到以下摘录的消息：

我在这里做错了什么吗?还是jars实际上从Maven存储库中丢失了？

Answer 1

我能够通过将<type>pom</type>添加到pom.xml来解决这个问题。我在OpenID4Java google组的这条线中找到了答案。

以下是谷歌团队中的帖子：

我的意思是，您应该将"pom“添加到openid4java在pom.xml中的依赖部分： org.openid4java openid4java--消费者0.9.6 pom < Openid4java-使用者/openid4java-server/.的类型。都是"pom“而不是"jar”。jar文件位于openid4java-nodeps中，它依赖于openid4java消费者/openid4java服务器.

Answer 2

由: org.sonatype.aether.resolution.DependencyResolutionException:引起的下列工件无法解析: org.openid4java:openid4java:jar:0.9.6，org.openid4java:openid4java-consumer:jar:0.9.6，org.openid4java:openid4java-server:jar:0.9.6，org.openid4java:openid4java-server-JdbcServerAssociationStore:jar:0.9.6，org.openid4java:openid4java-consumer-SampleConsumer:jar:0.9.6，org.openid4java:openid4java-server-SampleServer:jar:0.9.6:找不到org.openid4java:openid4java:jar:0.9.6 in

您需要在包含这些工件的项目中添加一个<repository>，或者将它们安装到本地存储库中。

试试https://oss.sonatype.org/content/repositories/openid4java/ (在MavenHowTo找到)

Answer 3

这就是我为使其编译和运行所做的工作：

1. 转到您的m2或maven中央存储库，
2. org->openID4java->openID4java->0.9.6，编辑openid4java-0.9.6.pom文件，并将pom添加到没有jar的依赖项中。
3. org->openID4java->openid4java-consumer-SampleConsumer->0.9.6和编辑openid4java-使用者-SampleConsumer-0.9.6.pom文件，并将pom添加到openId-使用者的工件中
4. org->openID4java->openid4java-openid4java-server-SampleServer->0.9.6和编辑openid4java-server-SampleServer-0.9.6.pom文件，并将pom添加到openid4java的工件中
5. org->openID4java->openid4java-server-JdbcServerAssociationStore-0.9.6并打开pom文件，并将pom添加到openID-服务器工件中。

融合Eclipse，然后右键单击project和maven并更新依赖关系，对于maven工具用户，可以直接编译并准备好滚动。
