尝试复制工件时出现Maven wagon错误

Question

我正在尝试使用Maven Wagon插件将工件复制到服务器上。

我设置如下：

<build>
<extensions>
    <extension>
       <groupId>org.apache.maven.wagon</groupId>
       <artifactId>wagon-ssh</artifactId>
       <version>${maven.wagon.version}</version>
 </extension>
</extensions>
    <plugins>
        <plugin>
               <groupId>org.apache.maven.wagon</groupId>
               <artifactId>wagon-maven-plugin</artifactId>
               <version>${maven.wagon.version}</version>
              <!--  <dependencies>
                    <dependency>
                        <groupId>org.apache.maven.wagon</groupId>
                        <artifactId>wagon-ssh</artifactId>
                        <version>${maven.wagon.version}</version>
                    </dependency>
               </dependencies> -->
               <configuration>
                    <serverId>appui</serverId>
                    <fromFile>${project.build.directory}</fromFile>
                    <includes>${project.build.finalName}.war</includes>
                    <url>scp://localhost:2221/</url>                     
                    <toDir>/opt/jboss/jboss-as-7.1.1.Final/standalone/deployments</toDir>
               </configuration>
               <executions>
                 <execution>
                   <id>upload-war-to-server</id>
                   <phase>upload</phase>
                   <goals>
                     <goal>upload-single</goal>
                   </goals>
                   <configuration>
                        <serverId>appui</serverId>
                        <fromFile>${project.build.directory}</fromFile>
                        <includes>${project.build.finalName}.war</includes>
                        <url>scp://localhost:2221/opt/jboss/jboss-as-7.1.1.Final/standalone/deployments</url>            
                    </configuration>
                 </execution>
               </executions>
        </plugin>

然而，当我运行这个程序时，我会得到以下错误：

我已经搜索了github，看看其他人是如何使用Maven Wagon的，我看不出我使用它有什么问题。

Answer 1

您对wagon-maven-plugin的配置不正确：<fromFile>需要是对文件的引用，而不是目录。此外，根据文档，没有<includes>标记。

如果您引用生成的Maven工件（${project.build.finalName}.war），则需要确保upload-single目标在package阶段之后执行（例如，deploy是合适的）。在您的配置中，您已将upload-single目标绑定到不存在的阶段"上传"。

这将是最终配置：

<plugin>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-maven-plugin</artifactId>
    <version>${maven.wagon.version}</version>
    <executions>
        <execution>
            <id>upload-war-to-server</id>
            <phase>deploy</phase>
            <goals>
                <goal>upload-single</goal>
            </goals>
            <configuration>
                <serverId>appui</serverId>
                <fromFile>${project.build.directory}/${project.build.finalName}.war</fromFile>
                <url>scp://localhost:2221/opt/jboss/jboss-as-7.1.1.Final/standalone/deployments</url>            
            </configuration>
        </execution>
    </executions>
</plugin>
