maven deploy时报错

    今天在发布maven工程的时候,很奇怪,因为在本地package,install等等都没问题,但是打包的时候就是报错,日志如下:

[ERROR]

    如果对于maven不太熟悉的同学会很苦恼,仔细看日志我们会发现如下的信息:

repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter

    意思是在pom文件中缺少distributionManagement标签,或者缺少-DaltDeployementRepositoty,说的是缺少deploy的地址,maven不知道你想要deploy到哪里,在pom文件中增加如下信息,就发布成功了.

 <distributionManagement>
        <repository>
            <id>nexus</id>
            <name>releases</name>
            <url>http://mvn2.qdingnet.com/nexus/content/repositories/releases</url>
            <uniqueVersion>true</uniqueVersion>
        </repository>
        <snapshotRepository>
            <id>nexus</id>
            <name>snapshots</name>
            <url>http://XXXXXXXXXXXXX/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

    为了补充知识,下面讲解一下关于distributionManagement及其配置的信息.

    用于配置分发管理，配置相应的产品发布信息,主要用于发布，在执行mvn deploy后表示要发布的位置,下面时几种配置形式.

• 配置到文件系统

<distributionManagement>
    <repository>
        <id>proficio-repository</id>
        <name>Proficio Repository</name>
        <url>file://${basedir}/target/deploy</url>
    </repository>
</distributionManagement>

• 使用ssh2配置

<distributionManagement>
    <repository>
        <id>proficio-repository</id>
        <name>Proficio Repository</name>
        <url>scp://sshserver.yourcompany.com/deploy</url>
    </repository>
</distributionManagement>

• 使用sftp配置

<distributionManagement>
    <repository>
        <id>proficio-repository</id>
        <name>Proficio Repository</name>
        <url>sftp://ftpserver.yourcompany.com/deploy</url>
    </repository>
</distributionManagement>

• 使用外在的ssh配置

<distributionManagement>
    <repository>
        <id>proficio-repository</id>
        <name>Proficio Repository</name>
        <url>scpexe://sshserver.yourcompany.com/deploy</url>
    </repository>
</distributionManagement>
