wagon-maven-plugin

<dependency>  
    <groupId>org.codehaus.mojo</groupId>  
    <artifactId>wagon-maven-plugin</artifactId>  
    <version>1.0</version>  
</dependency>

主要提供如下几个goal

wagon:upload-single uploads the specified file to a remote location.
wagon:upload uploads the specified set of files to a remote location.
wagon:download-single downloads the specified file from a remote location.
wagon:download downloads the specified set of files from a remote location.
wagon:list lists the content of a specified location in a remote repository.
wagon:copy copies a set of files under a Wagon repository to another.
wagon:merge-maven-repos merges , including metadata, a Maven repository to another.
wagon:sshexec Executes a set of commands at remote SSH host.

使用前需要在build中加入

<build>
    [...]
    <extensions>  
        <extension>  
            <groupId>org.apache.maven.wagon</groupId>  
            <artifactId>wagon-ssh</artifactId>  
            <version>2.8</version>  
        </extension>  
    </extensions> 
    [...]
</build>

文件上传到服务器

Maven项目可使用mvn package指令打包，打包完成后包位于target目录下，要想在远程服务器上部署，首先要将包上传到服务器。在项目的pom.xml中配置wagon-maven-plugin插件：

单个文件

<build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-ssh</artifactId>
            <version>2.8</version>
        </extension>
    </extensions>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>wagon-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <fromFile>target/test.jar</fromFile>
                <url>scp://user:password@server/home/xxg/Desktop</url>
            </configuration>
        </plugin>
    </plugins>
</build>

多个文件

<build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-ssh</artifactId>
            <version>2.8</version>
        </extension>
    </extensions>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>wagon-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <fromDir>target</fromDir>
                <includes>lib/*,Hermes-service.jar</includes>
                <!-- <excludes>*</excludes> -->
                <url>scp://user:password@server</url>
                <toDir>/home/xxg/Desktop</toDir>
            </configuration>
        </plugin>
    </plugins>
</build>

fromDir是要上传的文件所在的目录 includes是要上传的文件的规则 excludes是无需上传的文件的规则 toDir是上传到服务器的所在目录 fromFile是要上传到服务器的文件，一般来说是jar或者war包 url配置服务器的用户、密码、地址以及文件上传的目录。

配置完成后，运行命令：

mvn clean package wagon:upload-single

package、wagon:upload-single分别对项目进行打包和上传操作。命令运行结束后，文件就会成功上传到Linux服务器。

在服务器上执行Linux命令

部署项目不仅要把包传上服务器，而且还需要执行一些指令来启动程序。在程序启动之前，可能还需要将原来的程序关闭。

运行jar文件

启动jar包通常会使用java -jar test.jar命令，可以将命令配置在pom.xml中：

<build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-ssh</artifactId>
            <version>2.8</version>
        </extension>
    </extensions>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>wagon-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <fromFile>target/test.jar</fromFile>
                <url>scp://user:password@server/home/xxg/Desktop</url>
                <commands>
                    <!-- 杀死原来的进程 -->
                    <command>pkill -f test.jar</command>
                    <!-- 重新启动test.jar，程序的输出结果写到nohup.out文件中 -->
                    <command>nohup java -jar /home/xxg/Desktop/test.jar > /home/xxg/Desktop/nohup.out 2>&1 &</command>
                </commands>
                <!-- 显示运行命令的输出结果 -->
                <displayCommandOutputs>true</displayCommandOutputs>
            </configuration>
        </plugin>
    </plugins>
</build>

配置完成后，运行命令：

mvn clean package wagon:upload-single wagon:sshexec

package、wagon:upload-single、wagon:sshexec分别对项目进行打包、上传、运行command命令的操作。命令运行结束后，在服务器上查看进程ps -ef|grep test.jar，或者查看nohup.out文件，就可以看到Java程序在服务器上已经启动。

上传war包并启动Tomcat

如果是Web应用，可使用服务器上的Tomcat来部署。

<build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-ssh</artifactId>
            <version>2.8</version>
        </extension>
    </extensions>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>wagon-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <fromFile>target/javawebdeploy.war</fromFile>
                <!-- 上传到Tomcat的webapps目录下 -->
                <url>scp://user:password@server/coder/tomcat/apache-tomcat-7.0.55/webapps</url>
                <commands>
                    <!-- 重启Tomcat -->
                    <command>sh /coder/tomcat/apache-tomcat-7.0.55/bin/shutdown.sh</command>
                    <command>rm -rf /coder/tomcat/apache-tomcat-7.0.55/webapps/javawebdeploy</command>
                    <command>sh /coder/tomcat/apache-tomcat-7.0.55/bin/startup.sh</command>
                </commands>
                <displayCommandOutputs>true</displayCommandOutputs>
            </configuration>
        </plugin>
    </plugins>
</build>

完成以上配置后，同样可通过mvn clean package wagon:upload-single wagon:sshexec命令自动部署。

配置execution

如果你觉得mvn clean package wagon:upload-single wagon:sshexec命令太长了不好记，那么可以配置execution，在运行package打包的同时运行upload-single和sshexec。

<build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-ssh</artifactId>
            <version>2.8</version>
        </extension>
    </extensions>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>wagon-maven-plugin</artifactId>
            <version>1.0</version>
            <executions>
                <execution>
                    <id>upload-deploy</id>
                    <!-- 运行package打包的同时运行upload-single和sshexec -->
                    <phase>package</phase>
                    <goals>
                        <goal>upload-single</goal>
                        <goal>sshexec</goal>
                    </goals>
                    <configuration>
                        <fromFile>${project.build.directory}/${project.build.finalName}.${project.packaging}</fromFile>
                        <url>scp://user:password@server/coder/tomcat/apache-tomcat-7.0.55/webapps</url>
                        <commands>
                            <command>
                                <![CDATA[
                                    export JAVA_HOME=/opt/jdk1.8.0_121
                                    export PATH=$JAVA_HOME/bin:$PATH
                                    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
                                    cd /opt/mircroService/pcs && ./run.sh start
                                ]]>
                            </command>
                            <command>sh /coder/tomcat/apache-tomcat-7.0.55/bin/shutdown.sh</command>
                            <command>rm -rf /coder/tomcat/apache-tomcat-7.0.55/webapps/javawebdeploy</command>
                            <command>sh /coder/tomcat/apache-tomcat-7.0.55/bin/startup.sh</command>
                        </commands>
                        <displayCommandOutputs>true</displayCommandOutputs>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

配置完成后，即可使用mvn clean package来代替mvn clean package wagon:upload-single wagon:sshexec。

服务器独立配置

需要在Maven的配置文件settings.xml中配置好server的用户名和密码。

<server>  
    <id>webserver</id>  
    <username>hadoop</username>  
    <password>123</password>  
<!--
<configuration>
    diabled `The authenticity of host 'xxx' can't be established.Are you sure you want to continue connecting? (yes/no):`
    <strictHostKeyChecking>no</strictHostKeyChecking>
    or
    <knownHostsProvider implementation="org.apache.maven.wagon.providers.ssh.knownhost.NullKnownHostProvider">
        <hostKeyChecking>no</hostKeyChecking>
    </knownHostsProvider>
</configuration>
-->
</server>

然后configuration里面加上serverId，并且去掉url里面的用户名和密码。

<configuration>
    [...]
    <serverId>webserver</serverId>
    <url>scp://server</url>
    [...]
<configuration>
