nexus3 搭建遇到的一些问题

nexus3的坑

搭建好nexus3后，配置了~/.m2/settings.xml文件，和项目中的pom.xml文件。以下

• settings.xml

<?xml version="1.0" encoding="utf-8"?>
<settings>
    <servers>
        <!-- 这是公司的maven nexus 用户名密码 -->
        <server>
            <id>souban-nexus</id>
            <username>打码处理</username>
            <password>打码处理</password>
        </server>
        <!-- 这是我本身刚搭建的nexus仓库 用户密码 -->
        <server>
            <id>wooo-nexus</id> <!-- 这里的id和项目中pom配置的的id应该是同样的 -->
            <username>打码处理</username>
            <password>打码处理</password>
        </server>
    </servers>
    <mirrors>
         <mirror>
            <!-- aliyun 加速器 -->
            <id>aliyun-repository-public</id>
            <name>Maven Repository Manager running on aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
        <mirror>
            <!-- aliyun 加速器 -->
            <id>aliyun-repository-central</id>
            <name>Maven Repository Manager running on aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/repositories/central</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
    </mirrors>
</settings>

• pom.xml 这个pom文件是须要作打包上传的项目 tensquare_common

....
   <!-- 从哪里去拉jar包 -->
   <repositories>
       <repository>
           <id>wooo-nexus-snapshots</id>
           <name>release repository</name>
           <url>http://打码处理/repository/release/</url>
       </repository>
       <repository>
           <id>wooo-nexus-release</id>
           <name>snapshots repository</name>
           <url>http://打码处理/repository/snapshots/</url>
       </repository>
   </repositories>
   <!-- 须要打包上传到的目的地 -->
   <distributionManagement>
       <repository>
           <id>wooo-nexus</id>
           <name>release</name>
           <url>http://打码处理/repository/release/</url>
       </repository>
       <snapshotRepository>
           <id>wooo-nexus</id>
           <name>snapshots</name>
           <url>http://打码处理/repository/snapshots/</url>
       </snapshotRepository>
   </distributionManagement>
....

新建了两个format为maven(group)的仓库,如图:

随后我在pom文件中作了以下配置

<repositories>
        <repository>
            <id>wooo-nexus-snapshots</id>
            <name>release repository</name>
            <url>http://打码处理/repository/release/</url>
        </repository>
        <repository>
            <id>wooo-nexus-release</id>
            <name>snapshots repository</name>
            <url>http://打码处理/repository/snapshots/</url>
        </repository>
    </repositories>

    <distributionManagement>
        <repository>
            <id>wooo-nexus</id>
            <name>release</name>
            <url>http://手动打码/repository/release/</url> <!-- 更改了这一行-->
        </repository>
        <snapshotRepository>
            <id>wooo-nexus</id>
            <name>snapshots</name>
            <url>http://手动打码/repository/snapshots/</url>  <!-- 还有这一行-->
        </snapshotRepository>
    </distributionManagement>

而后再使用mvn deploy命令时, 报了以下的错:

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project tensquare_common: Failed to deploy artifacts: Could not transfer artifact io.wooo:tensquare_common:jar:0.0.4-20181116.063410-1 from/to wooo-nexus (http://手动打码/repository/snapshots/): Failed to transfer file: http://打码处理/repository/snapshots/io/wooo/tensquare_common/0.0.4-SNAPSHOT/tensquare_common-0.0.4-20181116.063410-1.jar. Return code is: 405, ReasonPhrase: PUT. -> [Help 1]

解决过程太复杂，不过赘述。直接说解决方案吧。我把配置中的url的/repository/snapshots换为了/repository/maven-snapshots，maven-snapshots如图： 这个是nexus自带的仓库还有一个maven-release也是。

按照网上的理解是，你建了一个group的仓库选择了maven-shapshots会指向该仓库，因而我就新建了上上个截图的两个仓库，而后在配置文件中配好就死活报错。 而后把配置改成了这样之后：

<repositories>
        <repository>
            <id>wooo-nexus-snapshots</id>
            <name>release repository</name>
            <url>http://手动打码/repository/release/</url>
        </repository>
        <repository>
            <id>wooo-nexus-release</id>
            <name>snapshots repository</name>
            <url>http://手动打码/repository/snapshots/</url>
        </repository>
    </repositories>

    <distributionManagement>
        <repository>
            <id>wooo-nexus</id>
            <name>release</name>
            <url>http://手动打码/repository/maven-release/</url> <!-- 更改了这一行-->
        </repository>
        <snapshotRepository>
            <id>wooo-nexus</id>
            <name>snapshots</name>
            <url>http://手动打码/repository/maven-snapshots/</url>  <!-- 还有这一行-->
        </snapshotRepository>
    </distributionManagement>

就没有报错了，因而我知道问题所在了。 而后我删了自带的maven-snapshots和maven-release，自建了下面两个仓库:

配置文件以下:

<repositories>
        <repository>
            <id>wooo-nexus-snapshots</id>
            <name>release repository</name>
            <url>http://手动打码/repository/release/</url>
        </repository>
        <repository>
            <id>wooo-nexus-release</id>
            <name>snapshots repository</name>
            <url>http://手动打码/repository/snapshots/</url>
        </repository>
    </repositories>

    <distributionManagement>
        <repository>
            <id>wooo-nexus</id>
            <name>release</name>
            <url>http://手动打码/repository/release/</url> <!-- 更改了这一行-->
        </repository>
        <snapshotRepository>
            <id>wooo-nexus</id>
            <name>snapshots</name>
            <url>http://手动打码/repository/snapshots/</url>  <!-- 还有这一行-->
        </snapshotRepository>
    </distributionManagement>

nexus配置以下，两个仓库配置是同样的。
