www.hibernatespatial.org is dead? What will be the solution?

Exception:
-------------
11:24:27.580 [INFO] [org.apache.http.impl.execchain.RetryExec] I/O exception (java.net.SocketException) caught when processing request to {}->http://www.hibernatespatial.org:80: Connection reset
11:24:27.580 [DEBUG] [org.apache.http.impl.execchain.RetryExec] Connection reset
java.net.SocketException: Connection reset
        at java.net.SocketInputStream.read(SocketInputStream.java:196)
        at java.net.SocketInputStream.read(SocketInputStream.java:122)

        at org.apache.http.impl.io.SessionInputBufferImpl.fillBuffer(SessionInputBufferImpl.java:155)

Root Cause Analysis:
--------------------------
The javadoc for SocketException states that it is

    Thrown to indicate that there is an error in the underlying protocol such as a TCP error

So, here the actual case is,
When the command "gradle bootRun" is trying to access this maven repo "http://www.hibernatespatial.org:80", it fails. Because this repo is dead.

Solution Procedure#1:
----------------------------
Hibernate Spatial has been merged into Hibernate ORM 5.0. The hibernatespatial.org site will be discontinued, along with the Maven Repository.

The ideal solution would be to upgrade to a 5.0.x version that is on maven central https://mvnrepository.com/artifact/org.hibernate/hibernate-spatial.

Solution Procedure#2:
----------------------------
As the repo is dead, so it is required to search for another repo which can give access for related file.

The versions 4.0 and 4.3 can be found on this repo: http://nexus.e-is.pro/nexus/content/groups/public/org/hibernate/hibernate-spatial/

You can choose 2nd solution procedure.

Now the build.gradle file looks like below:

    repositories {
        mavenCentral()
        mavenLocal()
        maven { url "http://repo.spring.io/snapshot" }
        maven { url "http://repo.spring.io/milestone" }
        maven { url "http://download.osgeo.org/webdav/geotools" }
        // maven { url "http://www.hibernatespatial.org/repository" } //dead link
        maven { url "http://nexus.e-is.pro/nexus/content/groups/public/" }
    }
