Jak mam zrobić pakiet dostępny do Gradle?

Answer 1

To chyba kwestia importu w kodzie źródłowym - Twój Gradle zbudować skrypt korzysta Wiosna Boot 1.3.6.RELEASE w którym SpringBootServletInitializer ma następującą nazwę pełną:

org.springframework.boot.context.web.SpringBootServletInitializer 

Twój Maven pom.xml jednak wykorzystuje Wiosna Boot 1.4.0.BUILD-SNAPSHOT, którego nazwa została zmieniona na pakiet:

org.springframework.boot.web.support.SpringBootServletInitializer 

więc jeśli przejdź do SampleJettyJspApplication i zmienić import do

import org.springframework.boot.context.web.SpringBootServletInitializer; 

wszystko powinno być w porządku.

Alternatywnie, można zmienić swój Gradle zbudować skrypt do importu 1.4.0.BUILD-SNAPSHOT, ale to wymagałoby dodania Wiosny kopiach repozytorium

buildscript { 
    repositories { 
     maven.url "http://repo.spring.io/snapshot" 
     mavenCentral() 
    } 

    dependencies { 
     classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.BUILD-SNAPSHOT") 
    } 
} 

Answer 2

należy użyć tego samego źródła wersji 1.4.0 startową .BUILD-SNAPSHOT jak w maven. org.springframework.boot.web.support.SpringBootServletInitializer został wprowadzony od wersji 1.4.0, dlatego gradle nie może go znaleźć.
