运行maven安装命令时出现“无法解析依赖项”错误

Question

我在pom.xml中添加了私有nexus存储库网址，以便从内部nexus存储库安装一些依赖项。

但是eclipse仍然在pom.xml文件中显示“丢失工件错误”消息

下面是我运行mvn安装命令时的命令行错误消息

[错误]无法对项目diffapi执行目标：无法解析项目com的依赖项。my:diffapi:jar:0.0.1-SNAPSHOT:无法解析以下工件：com。aaa。bbb。波伊。jar:poi:jar:5.14.4，com。aaa。bbb。波伊。jar:poiskp搜索客户端util:jar:5.14.4，com。aaa。bbb。波伊。jar:poi-util:jar:5.14.4，com。aaa。bbb。frame:ndds日志：jar:1.4.6，com。aaa。bbb。frame:ndds-util:jar:1.4.6，com。aaa。bbb。frame:ndds监控代理：jar:1.5.0，com。aaa。bbb。frame:nddsweb实用程序：jar:1.5.0，com。aaa。bbb。frame:ndds context:jar:1.5.0:找不到com。aaa。bbb。波伊。jar:poi:jar:5.14.4英寸https://repo.maven.apache.org/maven2已缓存在本地存储库中，在经过central的更新间隔或强制更新之前，不会重新尝试解析

似乎maven只访问maven central而不是私有nexus Repositories

这是我的pom.xml

Answer 1

您似乎混淆了构建后项目将部署在哪里的存储库与用作项目中依赖项来源的存储库。您实际上还没有指定自定义的第三方回购，所以Maven在未能在中央回购中找到工件后放弃了。从Maven留档：

repositories元素在POM中指定了Maven下载远程工件以供当前项目使用的位置和方式，而distributionManagement指定了该项目在部署时到达远程存储库的位置（以及方式）。如果未定义snapshotRepository，则存储库元素将用于快照分发。

因此，尝试添加一个

<project>
    ...
    <distributionManagement>
        <repository>
            <id>AAA-releases</id>
            <name>AAA-releases</name>
            <url>http://IP:PORT/nexus/content/repositories/AAA-releases/</url>
        </repository>
        <snapshotRepository>
            <id>AAA-snapshots</id>
            <name>AAA-snapshots</name>
            <url>http://IP:PORT/nexus/content/repositories/AAA-snapshots</url>
        </snapshotRepository>
    </distributionManagement>
    <repositories>
        <!-- fill in with the actual details of your repo here -->
        <repository>
            <id>REPO ID</id>
            <name>REPO NAME</name>
            <url>YOUR URL GOES HERE</url>
        </repository>
    </repositories>
</project>
