Run (deploy?) a "maven" .war in TOMCAT 8

First of all i don't have a clue about Maven, nor Tomcat, nor Java.

I have a .war file with a webpage and a Tomcat 8 server installed in a Mac (Yosemite). Is located at /Library/Tomcat/webapps/wm-admin-ui.war. I also have Maven (v3) installed and configured with a tomcat user.

I need to run the .war in a Tomcat server that apparently is intended to be deployed by some Maven plugin. I figured this out because there's a maven directory at META-INF and the usual deployment doesn't work at all. See picture below as reference.

Thing is,

Directory structure of '/Library/Tomcat/webapps/wm-admin-ui' :

The errors at the catalina.out log:

This is the code that throughs the error:

private String getSwaggerBasePath() {
    InputStream is = getClass().getResourceAsStream("/swagger.properties");
    Properties properties = new Properties();
    try {
        properties.load(is);
        is.close();
    } catch (IOException e) {
        LOGGER.error("Failed to handle stream for swagger.properties file ", e);
    }

    String context = properties.getProperty("swagger.base_path", "");

    return (StringUtils.isEmpty(context) ? "" : context) + "/wm-admin-ui/rest";
}

It seems that class com.toro.wm.configurations.WmWebApplicationInitializer with method getSwaggerBasePath has problem with load some property file.

Check this line in this class WmWebApplicationInitializer.java:86. Seems you haven't deployed crucial file and when application initialize context it demands that file.

Second problem is you need to put all properties in path WEB-INF/classes.

Now all should work.
