Question

我尝试构建一个Dropwizard应用程序，当我尝试在包含

之后使用mvn exec：java执行它时

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
        <configuration>
            <mainClass>${mainClass}</mainClass> //the application java class from properties tag 
            <arguments>
                <argument>server</argument>
            </arguments>
      </configuration>
</plugin>

使用mvn命令时在命令提示符下输入

> mvn exec：java 希望它可以构建和部署它，而是出现了以下问题

[INFO] --- exec-maven-plugin:1.6.0:java (default-cli) @ hello-dropwizard ---

这种行为有什么原因吗？

注意到我在系统中安装了Java 9，对休眠验证器类的研究很少，它期望返回8，因为我没有以特定的方式返回9，因为下面的代码

String[] specificationVersion = System.getProperty( "java.specification.version" ).split( "\\." );
return Integer.parseInt( specificationVersion[1] );

即使maven抛出了相同的异常，我也更改了PATH以包括java 1.8路径。我必须使用> mvn package 然后使用> java -jar target\dropwizarddemo.jar server

Dropwizard项目的Maven执行无法正常工作
