Tomcat & Eclipse : Can't run the server

Question

I had a working webapp but my project's Maven architecture wasn't correct so I decided to create a new one (I named it asteriskManagerV3). I copied my code into it and tried to run it with Tomcat but I always get this error : error when running the server

I tried lot of solutions but none worked.

Here is my web.xml in Tomcat :

 ...
<servlet>
    <servlet-name>MaServlet</servlet-name>
    <servlet-class>be.wavenet.MaServlet</servlet-class>
</servlet>


<!-- The mapping for the default servlet -->
<servlet-mapping>
    <servlet-name>MaServlet</servlet-name>
    <url-pattern>/actions</url-pattern>
</servlet-mapping>
...

web.xml in my project (/main/webapp/WEB-INF/web.xml)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

     <welcome-file>default.html</welcome-file>
     <welcome-file>default.htm</welcome-file>
  </welcome-file-list>
  <servlet>
    <description></description>
    <display-name>MaServlet</display-name>
    <servlet-name>MaServlet</servlet-name>
    <servlet-class>MaServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>MaServlet</servlet-name>
    <url-pattern>/actions</url-pattern>
  </servlet-mapping>
</web-app>

In Eclipse console I ge this error :

PS : I'm using Tomcat 8.5.28

this should get you started: Caused by: java.lang.IllegalArgumentException: The main resource set specified [/home/wvn/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/asteriskManagerV3] is not valid — Stultuske, Mar 22 '18 at 11:17
clean **.m2** folder clean server from your tomcat, update maven & try — Night Programmer, Mar 22 '18 at 11:24
@Stultuske I saw it but when I look into this "/home/wvn/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps" folder there is no "asteriskManagerV3" only a folder named root. — Gabriel, Mar 22 '18 at 11:25
@SandipND By "clean .m2", you mean delete the "repository" folder that is inside or run mvn clean or something else? Sorry ah ah! Thanks for your help ;) — Gabriel, Mar 22 '18 at 11:27
refer **https://stackoverflow.com/questions/12340128/failed-to-start-component-standardenginecatalina-standardhostlocalhost-stan/35646457** — Night Programmer, Mar 22 '18 at 11:29
@SandipND This person had an "Caused by: java.lang.NoClassDefFoundError: org/apache/commons/digester/RuleSet" error. I looked at proposed solutions and unfortunatly none worked. My error is "Caused by: java.lang.IllegalArgumentException: The main resource set specified [/home/wvn/eclipse-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/asteriskManager] is not valid". — Gabriel, Mar 22 '18 at 13:13
Remove the ` ` tag from your `web.xml` (projects). Just keep the `servlet` tag. See what happens. — hiren, Mar 24 '18 at 11:02
Nice try but it didn't work. Thanks for having tried though. (Still struggling with this error btw...) — Gabriel, Apr 06 '18 at 07:02
