How should I make the package available to gradle?
我应该如何使包可用于 gradle？
采纳答案by Milo? Milivojevi?
It's probably an import issue in your source code - your Gradle build script uses Spring Boot 1.3.6.RELEASE in which SpringBootServletInitializer has the following fully qualified name:
这可能是您的源代码中的导入问题 - 您的 Gradle 构建脚本使用 Spring Boot 1.3.6.RELEASE，其中 SpringBootServletInitializer 具有以下完全限定名称：
org.springframework.boot.context.web.SpringBootServletInitializer
Your Maven pom.xml, however, uses Spring Boot 1.4.0.BUILD-SNAPSHOT, in which the package name was changed to:
但是，您的 Maven pom.xml 使用 Spring Boot 1.4.0.BUILD-SNAPSHOT，其中包名称更改为：
org.springframework.boot.web.support.SpringBootServletInitializer
So if you go to your SampleJettyJspApplication and change the import to
因此，如果您转到 SampleJettyJspApplication 并将导入更改为
import org.springframework.boot.context.web.SpringBootServletInitializer;
everything should be fine.
一切都应该没问题。
Alternatively, you could alter your Gradle build script to import 1.4.0.BUILD-SNAPSHOT, but that would require adding Spring's snapshot repository:
或者，您可以更改 Gradle 构建脚本以导入 1.4.0.BUILD-SNAPSHOT，但这需要添加 Spring 的快照存储库：
buildscript {
repositories {
maven.url "http://repo.spring.io/snapshot"
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.BUILD-SNAPSHOT")
}
}
回答by Issam EL-ATIF
You should use the same spring boot version 1.4.0.BUILD-SNAPSHOT as in maven. org.springframework.boot.web.support.SpringBootServletInitializerwas introduced since 1.4.0 that's why gradle cannot find it.
您应该使用与 maven 中相同的 Spring Boot 版本 1.4.0.BUILD-SNAPSHOT。org.springframework.boot.web.support.SpringBootServletInitializer从 1.4.0 开始引入，这就是 gradle 找不到它的原因。
