运行

时有不同的行为
mvn clean tomcat7:run-war and mvn clean tomcat7:run

我正在尝试在servlet 3容器中运行jstls(因此是tomcat 7插件),出于某种原因,当我使用tomcat7:run命令运行插件时,我得到了这个异常:

org.apache.jasper.JasperException: Unable to read TLD "META-INF/c.tld" from JAR file "file:/...../.m2/repository/jstl/jstl/1.2/jstl-1.2.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(AbstractSAXParser.java:469)

鉴于tomcat7:run-war,我不这样做。我怀疑它与类浏览器有关,在运行选项中查看类路径的maven存储库与战争爆炸位置

target\[webappname]\WEB-INF\lib

使用run-war的主要原因是对tagx或JSTL标记的更改进行了热部署。

以下是相关的pom.xml包含:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.2</version>
    </dependency>

        <dependency>
            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
          </dependency>

        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>

                <path>/webapp</path>
            </configuration>
