带有maven的Eclipse Dynamic Web Project在mvn tomcat7:run上抛出错误

Question

我在eclipse Luna中创建了一个动态Web项目,然后将其转换为maven项目.我指定了依赖项如下:

<dependencies>
    <dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>9.3-1102-jdbc41</version>
    </dependency>

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

并且还更新了tomcat7插件

<plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.0</version>
        <configuration>
          <port>8080</port>
          <path>/</path>
        </configuration>
      </plugin>

但经过mvn clean install之后mvn tomcat7:run我得到了以下错误:

SEVERE: Error starting static Resources

我知道没有目录,src/main/webapp因为它不是经典的maven webapp.如何避免此错误并像往常一样正常启动我的tomcat7？

Answer 1

如果您没有使用标准的webapp文件夹,请指示插件使用您的Web资源所在的目录.以下内容应该修复它.

  <plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.0</version>
    <configuration>
      <port>8080</port>
      <path>/</path>
      <warSourceDirectory>src/mywebappfolder</warSourceDirectory>
    </configuration>
  </plugin>
