[FIXED] Can't start boot project where network is close

Issue

I've created Spring boot application. It's simple:

plugins:

apply plugin: 'war'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

And in my build script:

buildscript {
    dependencies {
            classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.3.RELEASE")
    }
}

and dependencies:

compile("org.springframework.boot:spring-boot-devtools")
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter-security")
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'

Additionally I have dependencies like: lambok, h2, webjars etc. Nothing interesting.

So in my local machine:

• In my local machine I build war file!
• Everything is fine! no problem at all!

I have no problems at all! BUT when I deploy it at the server where "THERE IS NO NETWORK"

Any idea how can I solve the problem?

Just simple web application without any XML configurations.

Solution

You can put the xsd in your classpath on the server without network connectivity. The XSD url is only used when a local classpath copy of the xsd is not found.

There are also details on registering schemas, but this is probably overkill.
