Eclipse Dynamic Web Project with maven is throwing error on mvn tomcat7:run


I created a dynamic web project in eclipse Luna and then converted the same to maven project. I specified dependencies as follows:

<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>

and also updated tomcat7 plugin as

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

but after mvn clean install followed by mvn tomcat7:run I got the following error:

SEVERE: Error starting static Resources

I know there is no directory as src/main/webapp as it is not classical maven webapp. How can I avoid this error and start my tomcat7 normally as usual?


Solution

  • In case you are not using the standard webapp folder, instruct the plugin to use the directory where your web resources are located.Something like the below should fix it.

      <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>
