Maven运行Ant脚本非调试模式下无法显示完整常规日志

问题说明 #

将Ant项目迁移到Maven后，使用maven-antrun-plugin运行原build.xml时，非调试模式下无法看到Ant原生的Target调用日志（如default:、target1:这类标识），仅能看到具体任务的执行日志，无法追踪Target的调用流程。

解决方案 #

maven-antrun-plugin默认将Ant的Target启动/结束日志归类为DEBUG级别，常规INFO日志模式下会被过滤。以下两种方法可解决该问题：

方法1：配置插件日志级别 #

修改pom.xml中maven-antrun-plugin的配置，添加日志器设置，将Ant的Project日志级别设为INFO，这样就能在Maven常规日志中显示Target调用信息：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>${version.org.apache.maven.plugins.maven-antrun-plugin}</version>
  <dependencies>
    <!-- 保留原有依赖配置 -->
  </dependencies>
  <executions>
    <execution>
      <id>temp</id>
      <phase>install</phase>
      <configuration>
        <!-- 添加日志器配置，开启Ant Target日志 -->
        <loggers>
          <logger name="org.apache.tools.ant.Project" level="INFO"/>
        </loggers>
        <target>
          <ant antfile="${project.basedir}${file.separator}build.xml"/>
        </target>
      </configuration>
      <goals>
        <goal>run</goal>
      </goals>
    </execution>
  </executions>
</plugin>

方法2：在Ant任务中指定日志级别 #

直接在<ant>调用时添加loglevel="info"属性，强制Ant以INFO级别输出日志，无需修改插件全局配置：

<target>
  <ant antfile="${project.basedir}${file.separator}build.xml" loglevel="info"/>
</target>

验证效果 #

修改配置后执行mvn clean install，日志中将显示Ant的Target调用信息，与原生Ant运行时的输出一致：
