如何强制Sonatype Nexus更新？

Question

我想在我的pom.xml中使用onejar-maven-plugin:

<plugin>
    <groupId>org.dstovall</groupId>
    <artifactId>onejar-maven-plugin</artifactId>
    <version>1.4.4</version>
    <executions>
        <execution>
            <configuration>
                <mainClass>com.exmaple.myproj.MpPort_MpSoapPort_Client</mainClass>
                <onejarVersion>0.97</onejarVersion>
                <attachToBuild>true</attachToBuild>
                <classifier>onejar</classifier>
            </configuration>
            <goals>
                <goal>one-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

<pluginRepositories>
    <pluginRepository>
        <id>onejar-maven-plugin.googlecode.com</id>
        <url>http://onejar-maven-plugin.googlecode.com/svn/mavenrepo</url>
    </pluginRepository>
</pluginRepositories>

但由于某种原因,尝试通过Eclipse Maven插件(Maven安装)构建它会导致BUILD ERROR:

所以我手动下载了onejar-maven-plugin.jar并通过命令行安装它,我似乎得到了一个类似的错误:

我的理解是因为我们有一个Nexus镜像,它不包含那个特殊的神器,所以事情会变得混乱.

所以我尝试按照如何强制Sonatype Nexus重新生成/重新索引其元数据的说明,但"浏览索引"选项卡没有这样的上下文菜单!在我们的Sonatype Nexus上.

我在这里读到"Nexus只缓存客户要求的工件.所以你需要设置你的项目poms来请求正确的版本".但这正是我一直在做的事情 - 结果没有任何改变.

如何摆脱这种"鸡蛋和鸡蛋"的情况并获得这个onejar-maven-plugin ver.1.4.4进入我的Nexus镜像？

(或者,如何将其放入我的本地.m2缓存？)

Answer 1

即使本地存储包含有关-U不可用的工件的元数据,您也可以强制Maven再次更新和请求依赖关系

mvn clean install -U 

应该管用.

此外,您应该更改settings.xml为指向公共组而不是直接指向中央存储库.更多内容可以在Nexus书中找到.

您应该注意,Central Repository没有onejar您尝试使用的插件.退房的搜索结果,并了解groupId是com.joilira不org.dstovall

如果你真的想使用你的onejar插件,org.dstovall你应该添加网址http://onejar-maven-plugin.googlecode.com/svn/mavenrepo/作为Nexus的代理存储库,将其添加到公共组然后使用你公共团体settings.xml
