Unable to deploy web application to tomcat7 on debian virtual server - maven

Question

I am writing simple Java backend using jersey and I want to deploy it to a virtual server, running Debian. I think, I have tomcat7 installed properly together with tomcat7-admin and also set the user roles correctly (manager-gui and manager-script).
I can see tomcat running, when I visit http://my-ip-address:8080. I also can access manager through http://my-ip-address:8080/manager/html, so I think the tomcat is configured properly.
The problem is that when I want to deploy my web application (using tomcat7-maven-plugin), the deployment itself doesn't work. here is trace from maven:
[INFO] tomcatManager status code:200, ReasonPhrase:OK
[INFO] FAIL - Failed to deploy application at context path /parser

Here is also the content of catalina log about the thing:

I have no idea what errors above means, because I was able to deploy this app to my local tomcat using idea (not maven-tomcat-plugin). I will try to provide as many information as needed, because I need to fix this rather quickly.
I read some threads about similar failures and there, the solution was to set the scope of javax.servlet-api to provided. In my pom.xml I didn't have this dependency, as jersey-servlet already has it as provided, so I have no other ideas on how to fix this.
Here is my actual pom:

Thanks in advance

You should have tomcat7-maven-plugin in plugins not in dependencies see the usage page. Remove from dependencies and try
