Maven无法解析依赖项,无法解析工件

Question

Maven无法解析依赖项,无法解析工件

这应该是我朋友的一个工作项目.他在我面前展示了项目,然后我复制了项目,将其作为现有的maven项目导入(我使用的是m2eclipse插件).

然后,发生此错误.每次我尝试使用maven构建内容时都可以重现此错误.

执行mvn依赖:tree,dependency:list或通常的构建包将导致相同的错误.

从eclipse运行'package'构建的错误是:

我已经尝试下载最新版本的maven,并将它包含在eclipse helios中,但仍然是同样的问题.即使我在shell命令行(在eclipse之外)运行它也会发生相同的错误消息.

我错过了什么？

Answer 1

看起来你错过了一些Maven回购.询问你的朋友.m2/settings.xml,你可能想要更新POM以在那里包含存储库.

--edit:经过一些快速谷歌搜索后,尝试将其添加到您的POM:

<repository>
    <id>com.springsource.repository.bundles.release</id>
    <name>SpringSource Enterprise Bundle Repository - SpringSource Bundle Releases</name>
    <url>http://repository.springsource.com/maven/bundles/release</url>
</repository>
<repository>
    <id>com.springsource.repository.bundles.external</id>
    <name>SpringSource Enterprise Bundle Repository - External Bundle Releases</name>

我知道这是一个存储库问题,因为"POM for xxx is missing"警告消息.所以我只是搜索了"springsource maven"并提出了springource项目常见问题解答,以及将其设置为与Maven一起工作的条目. (6认同)
谢谢 !我的朋友提到它在他的笔记本电脑上工作,因为他已经在.m2 /中缓存了依赖项,并且maven不再尝试下载它们.并且他分享了存储库条目,有些就像你的发现,现在它现在运行良好..谢谢你的时间!如果我知道,您使用哪些关键字来找出要使用的存储库？昨天我也尝试使用谷歌搜索,但我最终痛苦不堪.哈哈 (5认同)

Maven将您的文件保存在缓存中,不要重试下载它们.您只需删除.m2目录即可手动"帮助"他,然后我们的朋友将通过旧的依赖项下载所有内容.

mvn clean install -U

解决了我的问题。由于 repos 被缓存，我需要强制它获取最新版本。

Answer 4

shi*_*iri 7

作为同一问题的替代来源,这个答案引用了使用Maven 3和Maven 2作为此问题的潜在原因.接近我可以说,这是由于Maven 3中更改的本地存储库解析更改.将此放在此处,以防其他任何人谷歌搜索并达到此答案(就像我一样).

手动下载jar，然后从jar所在的文件夹中执行命令：

mvn install:install-file -Dfile=*jar_file_name*.jar-DgroupId=*group_id* -DartifactId=*artifact_id* -Dversion=*version_no* -Dpackaging=jar

在jar file，jar_file_name，group_id，artifact_id和version_no可从Maven仓库页面。

在artifactId为所有下载失败的依赖关系是不正确的-因为某些原因，他们的前缀为com.springsource。剪切/粘贴问题？

您可以尝试按以下方式替换它们。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>jta</artifactId>
    <version>1.1.0</version>
</dependency>

如果这些工件在指定的存储库中不可用，您可能还想为其添加Maven中央存储库。
