java - jspc-maven-plugin 没有执行？

Question

我在我的 pom.xml 中添加这样的 jspc 插件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            <plugin>

               <artifactId>jspc-maven-plugin</artifactId>
               <version>2.0-alpha-3</version>
               <executions>
                  <execution>
                  <phase>compile</phase>
                     <goals>
                        <goal>compile</goal>
                     </goals>
                  </execution>
               </executions>
               <configuration>
                  <inputwebxml>${basedir}/src/main/webapp/WEB-INF/web.xml</inputwebxml>
                  <sources>
                     <directory>${basedir}/src/main/webapp/jsp</directory>
                     <includes>
                        <include>**/*.jsp</include>
                     </includes>
                  </sources>
               </configuration>
               <dependencies>
                  <dependency>
                     <groupId>org.codehaus.mojo.jspc</groupId>
                     <artifactId>jspc-compiler-tomcat6</artifactId>
                     <version>2.0-alpha-3</version>
                  </dependency>
               </dependencies>
            </plugin>
         </plugins>
      </pluginManagement>
   </build>
</project>

但是，当我运行 mvn clean dependency:copy-dependencies install 时，我没有看到生成任何类。从这里，http://hasini-gunasinghe.blogspot.com/2011/09/how-to-use-pre-compiled-jsps-in-webapp.html ，我应该看到一个 target/jsp-source 目录，但我没有。

我的 pom.xml 有问题吗？

Answer 1

问题是您在 <pluginManagement> 中声明插件并且它没有在 <plugins> 中声明.引用 Maven 文档(强调我的):

Plugin Management contains plugin elements in much the same way, except that rather than configuring plugin information for this particular project build, it is intended to configure project builds that inherit from this one

这里不是这种情况。

因此，您只需删除 <pluginManagement>元素并让插件直接在 <plugins> 中声明.

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo.jspc</groupId>
            <artifactId>jspc-maven-plugin</artifactId>
            <version>2.0-alpha-3</version>
            <!-- rest of configuration -->
        </plugin>
    </plugins>
</buil>
