Java 在maven生成期间执行shellscript时出错

我试图在maven构建期间在远程linux服务器中执行shell脚本

以下是我在pom.xml中用于此目的的代码

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
     <execution>
            <id>server-copy</id>
            <goals>
                <goal>run</goal>
            </goals>
            <phase>process-sources</phase>
            <configuration>
            <tasks>

            <sshexec host="hostserver" username="user" trust="true" 
                        password="password" failonerror="true"  timeout="1200"
                        command="sh /pathofshellscript/test.sh"/> 
            </tasks>
            </configuration>
        </execution>
<executions>

当我执行maven构建时，它会在控制台中请求Kerberos用户名和密码。我不知道为什么它要求用户名和密码，因为我已经在pom.xml中提供了。有什么我遗漏的吗？

使用-X开关重新运行Maven，以启用完整调试日志。希望各个用户都有删除shell脚本的可执行权限。
