我有一个旧的struts
1应用程序，该应用程序始终使用Ant构建，我将其转换为使用Maven。我的应用程序的结构是模块化的，在包含的模块中具有依赖项管理。包含模块的dep
mgmt部分包含：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.0.1</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
        ...
    </dependencies>
</dependencyManagement>

构建战争（package从包含的模块运行Maven作业）并从intelliJ运行具有该战争的Tomcat配置时，我在浏览器中看到以下内容：

org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP

通过搜索可以发现的所有内容都表明，原因是javax.servlet jars中的版本冲突，但是我的WEB-INF /
lib目录中根本没有任何内容。我一直在使用的范围尝试provided，compile甚至install/pom，但那些没有做任何帮助。

Tomcat日志中没有其他内容。

我确认正在编译jsps。我正在使用jspc-maven-plugin。

在我的子模块（而不是包含子模块）的pom.xml中，我具有：

<build>
    <!-- default goal to run if somebody doesn't pick one (rarely matters) -->
    <defaultGoal>install</defaultGoal>

    <!-- resources and filtering - also see configuration under maven-war-plugin below -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    <filters>
        <filter>src/main/resources/${env}.properties</filter>
        <filter>src/main/resources/${env}.tokens</filter>
    </filters>

    <plugins>
        <!-- begin - precompiling jsps -->
        <plugin>

                        <goal>compile</goal>
                    </goals>

                        <!--<workingDirectory>${basedir}/src/main/webroot</workingDirectory>-->
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <!-- end - precompiling jsps -->

        <!-- used to build warfiles -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.0</version>
            <configuration>
                <webResources>
                    <resource>
                        <directory>${pom.basedir}/src/main/webroot</directory>
                        <filtering>true</filtering>
                        <!--<targetPath>WEB-INF</targetPath>-->
                    </resource>
                </webResources>
            </configuration>
        </plugin>
    </plugins>
</build>

我可以在Maven构建输出中看到正在编译jsps。但是我仍然得到JasperException。
