maven deploy時報錯

    今天在發佈maven工程的時候,很奇怪,由於在本地package,install等等都沒問題,可是打包的時候就是報錯,日誌以下:

    若是對於maven不太熟悉的同窗會很苦惱,仔細看日誌咱們會發現以下的信息:

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

    意思是在pom文件中缺乏distributionManagement標籤,或者缺乏-DaltDeployementRepositoty,說的是缺乏deploy的地址,maven不知道你想要deploy到哪裏,在pom文件中增長以下信息,就發佈成功了.

 <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>

    爲了補充知識,下面講解一下關於distributionManagement及其配置的信息.

    用於配置分發管理，配置相應的產品發佈信息,主要用於發佈，在執行mvn deploy後表示要發佈的位置,下面時幾種配置形式.

• 配置到文件系統

<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>
<build>
    <extensions>
        <extension>

            <artifactId>wagon-ssh-external</artifactId>
            <version>1.0-alpha-6</version>
        </extension>
    </extensions>
</build>

• 使用ftp配置

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