Question

我正在尝试取消部署并使用jboss-as-maven-plugin将war文件部署到jboss EAP 6，并在我的项目pom.xm中提到了以下行。如果WAR尚未部署并且在jboss中可用，则Undeploy cli步骤将失败。如果WAR不存在，我希望跳过此步骤，并在后续步骤中继续进行新部署。有什么想法解决这个问题吗？

Answer 1

我自己没有尝试过，但是通过查看https://docs.jboss.org/jbossas/7/plugins/maven/latest/examples/complex-example.html中的maven插件文档，我认为你只是缺少一个额外的配置子元素，即：

<configuration>
    <ignoreMissingDeployment>true</ignoreMissingDeployment>
</configuration>

我能够通过在我的pom.xml中仅添加以下行来解决这个问题，这些行将替换已部署的组件并在不存在的情况下部署新组件

            <executions>
            <execution>                      
                <id>upload-war</id>
                <phase>deploy</phase>
                <goals>
                    <goal>deploy</goal>
                </goals> 
            <configuration>
                <filename>xxx.war</filename>
                <deployEnabled>false</deployEnabled>
                <ignoreMissingDeployment>true</ignoreMissingDeployment>
                <force>true</force>
                    <domain>
                        <server-groups>
                            <server-group>web-server-group</server-group>
                        </server-groups>
                    </domain>
            </configuration>
            </execution>    
        </executions>

注意：如果您没有提及文件名标签，那么将采用默认项目名称进行部署

如果战争不存在，则取消部署jboss cli会失败
