Question

在maven项目中，我在运行mvn包时收到以下错误：

[ERROR] Failed to execute goal org.codehaus.mojo:jspc-maven-plugin:1.4.6:compile (jspc) on project cto-reporting: Execution jspc of goal org.codehaus.mojo:jspc-maven-plugin:1.4.6:compile failed: A required class was missing while executing org.codehaus.mojo:jspc-maven-plugin:1.4.6:compile: org/apache/commons/logging/LogFactory

从父母pom我得到以下信息：

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jspc-maven-plugin</artifactId>
    <executions>
      <execution>
        <id>jspc</id>
        <goals>
          <goal>compile</goal>
        </goals>
        <configuration>
          <source>1.5</source>
          <target>1.5</target>
          <webFragmentFile>C:\temp\web-fragment.xml</webFragmentFile>
          <outputWebXml>C:\temp\jspweb.xml</outputWebXml>
        </configuration>
      </execution>
    </executions>
    <configuration>
      <source>1.5</source>
      <target>1.5</target>
      <webFragmentFile>C:\temp\web-fragment.xml</webFragmentFile>
      <outputWebXml>C:\temp\jspweb.xml</outputWebXml>
    </configuration>
  </plugin>

我试图在我的pom中添加commons-logging，即使它已经在父pom中了，我仍然得到同样的错误。有谁知道什么可能是错的？以前该项目运作良好。

Answer 1

出错的原因是我改为Maven 3.0.5，项目是在maven 2.2.1中创建的。所以通过改回2.2.1，一切都解决了。

由于缺少类，jspc-maven-plugin无法编译
