maven release插件将一版本发布到仓库中时Return code is: 401, ReasonPhrase:Unauthorized

需要在maven的setting.xml中配置servers.server节点,其值为nexus的对应的repository的id以及用户名及密码

<servers>
    <server>
        <id>releases</id>
        <username>admin</username>
        <password>admin</password>
    </server>
    <server>
        <id>snapshots</id>
        <username>deployment</username>
        <password>deployment</password>
    </server>
</servers>

mvn release:prepare -Pxxxx 将用setting.xml中定义的profile为我们提交,打tag,升级pom,再提交的一连串动作(但不要忘了setting.xml的profile定义及pom.xm中定义好maven-release-plugin的tagBase,username,password以及每个模块的scm信息)

maven conf/setting.xml

<profiles>
    <profile>
        <id>xxxx</id>
        <properties>
            <svn.name>username</svn.name>
            <svn.pwd>password</svn.pwd>
        </properties>
    </profile>
</profiles>

项目 pom.xml (让子模块都继承自另一个模块,类型为pom,假定名称为parent)

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>xxx.xx.xxx</groupId>
        <artifactId>xxxx</artifactId>
        <version>0.3-SNAPSHOT</version>
    </parent>
    <groupId><u><span style="color:#0066cc;">xxx.xx.xxx</span></u></groupId>
    <artifactId>parent</artifactId>
    <name>parent</name>
    <packaging>pom</packaging>
    <scm>
        <connection>scm:svn:https://192.168.1.88/svn/xxxx/trunk/parent</connection>
        <url>https://192.168.1.88/svn/xxxx/trunk/parent</url>
    </scm>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-release-plugin</artifactId>
                <configuration>
                    <tagBase>https://192.168.1.88/svn/xxxx/tags/</tagBase>
                    <username>${svn.name}</username>
                    <password>${svn.pwd}</password>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

这样mvn release:perform时maven-release-plugin会自动帮我们签出刚才打的tag，然后打包，分发到远程Maven仓库中(nexus).

注意：如果要把快照版本也发布到存储库，需要在trunk中执行mvn deploy，并且一定要配置snapshotRepository
