Check your classpath, you probably have Servlets API in version 2.x (2.4,
2.5). This method was added in Servlets 3.0
(https://docs.oracle.com/javaee/7/api/javax/servlet/ServletContext.html#getJspConfigDescriptor--),
and Jetty 9.2.14.v20151106 (the version that GWT uses) actually needs
Servlets 3.1.0
(https://search.maven.org/#artifactdetails%7Corg.eclipse.jetty%7Cjetty-project%7C9.2.14.v20151106%7Cjar)
(GWT 2.7.0 was using Jetty 8.1.12.v20130726, which BTW already needed
Servlets
3.0
https://search.maven.org/#artifactdetails%7Corg.eclipse.jetty%7Cjetty-project%7C8.1.12.v20130726%7Cjar,
but could have maybe worked OK with Servlets 2.5 – I doubt it, maybe you
changed the order of JARs in your classpath when upgrading; GWT 2.7 used to
bundle the Servlets API into gwt-dev, and this has changed in 2.8.1, when
retrieved from the Central Repository)
2) when i try to compile the project i get this exception

As someone told you already on StackOverflow, HasMetaData has been removed
from GWT 2.8, after being deprecated for more than 8 years!
(https://github.com/gwtproject/gwt/commit/aa1113205c3c2494d29a8c74cb368fdb497249f8)
You need to either update your gwt-maps dependency (if possible, but it's
been unmaintained for years too, I have no idea of its compatibility story)
or switch to another Google Maps integration library (or write yours using
JsInterop).
