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

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>
