我试图复活一个旧的项目。我想使用Maven来管理依赖/构建等。，我已经走了很远，但是现在我遇到了一个错误，我似乎无法解决，我似乎找不到任何关于:
在项目scanit上执行目标失败:无法解析项目net.cbojar:scanit:jar:0.2:无法找到工件javax.persistence:ejb:jar:3.0-public-draft-20060327在maven2 (http://repo1.maven.org/maven2/)
它想下载一个ejb-3.0-public-draft-20060327.jar文件，但是这个文件在repo中不存在。
我对maven比较陌生，我想用这个作为实践，但我现在把自己画进了一个角落。下面是我的pom.xml文件。

既然要将现有项目转换为Maven，就应该尊重原始依赖项。这意味着将与原始依赖项完全相同的版本添加为Maven依赖项，并排除未使用的传递依赖项(因为原始项目不需要它，并且它可以正常工作，那么我们可以安全地将它们从pom中排除)。
表明javax.persistence:ejb:jar:3.0-public-draft-20060327是org.hibernate:hibernate-annotations:3.1beta9的传递依赖关系。如果原始项目不需要它，您可以像这样将它从pom中排除:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.1beta9</version>
<exclusions>
<exclusion>
<groupId>javax.persistence</groupId>
<artifactId>ejb</artifactId>
<exclusion>
</exclusions>
</dependency>
删除
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.1beta9</version>
</dependency>
和使用:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
这就是导致这个问题的依赖项。这是2006年的。我还建议您将依赖项版本更新到最新版本。
编辑
由于这样的升级可能会破坏您的代码，并且没有进一步的细节，您可能应该坚持使用更接近您试图使用的版本。
查看maven repo中所有可用的hibernate注释版本。
你可能需要在你的项目pom.xml:
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>ejb-3.0-public-draft</artifactId>
<version>20050627</version>
<type>pom</type>
</dependency>
