Question

我注意到每次在MAVEN中运行我的exec：java命令时都会收到此警告。

[警告]警告：现在不推荐使用killAfter。你需要它吗？请评论MEXEC-6。

我该怎样摆脱它？我一直在寻找它，但没有任何线索。

的pom.xml：

Answer 1

要摆脱此警告，您需要修改pom.xml

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.3.2</version>
      <executions>
        <execution>
          <goals>
            <goal>java</goal>
          </goals>
        </execution>
      </executions>
      <configuration>
        <!--
          to get rid of the warning: [WARNING] Warning: killAfter is now deprecated. Do you need it ? Please comment on MEXEC-6.
          see: method execute() in https://github.com/ispringer/exec-maven-plugin/blob/master/src/main/java/org/codehaus/mojo/exec/ExecJavaMojo.java
        -->
        <killAfter>-1</killAfter>
        <mainClass>foodfinder.client.Launcher</mainClass>
      </configuration>
  </plugin>

修改对于exec-maven-plugin的较新版本（＆gt; 1.3.2），此答案不再有效。

对于下来选民，请看一下时间表。

Jul 2014 - release of plugin version 1.3.2
Nov 2014 - posting this answer
Mar 2015 - release of plugin version 1.4.0

Answer 2

更新到exec-maven-plugin的1.4.0版。警告不再出现。

Answer 3

选择一个：

1）通过添加：

来更改pom中的exec-maven-plugin配置

<killAfter>-1</killAfter>

2）或添加命令行参数：

-Dexec.killAfter=-1

killAfter运行exec：java时不推荐使用警告
