这是我的 build.gradle

plugins {

apply plugin: 'jetty'
apply plugin: "net.ltgt.apt"
apply plugin: "org.springframework.boot"
bootRepackage.enabled=false
apply plugin: "com.github.johnrengelman.shadow"



def jdkVersion = 1.8

sourceCompatibility = jdkVersion
targetCompatibility = jdkVersion

jettyRun {
     httpPort = 8080
}

repositories {
    mavenCentral()
}

sourceSets.all { set ->
    def jarTask = task("${set.name}Jar", type: Jar) {
        baseName = baseName + "-$set.name"
        from set.output
    }

    artifacts {
        archives jarTask
    }

}

sourceSets {
    main {
        java {
            srcDir 'src/main/java'
            srcDir project(':pointin-infrastructure').file('src/main/java')
        }
        resources {
            srcDir 'src/main/resources'
        }
        output.classesDir   = 'build/classes/main/java'
        output.resourcesDir = 'build/classes/main/resources'
    }
    test {
        java {
            srcDir 'src/test/java'
        }
        resources {
            srcDir 'src/test/resources'
        }
        output.classesDir   = 'build/classes/test/java'
        output.resourcesDir = 'build/classes/test/resources'
    }

}

这是我的主文件

package com.dxc.pt.application.config;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}

我正在尝试在 tomcat 8 上部署它，但它没有加载，因为我无法在战争中获取 lib 提供的文件夹。请不要说我对 gradle 很陌生

【问题讨论】：

所有sourceSets { } 块都应该被删除，因为它要么是错误的，要么只指定了与默认值相同的值。这：srcDir project(':pointin-infrastructure').file('src/main/java') 不是你依赖另一个项目的方式，当你做 compile project(':pointin-infrastructure') 时你已经拥有了。
我同意@nickb，我认为 sourceSets 主要是作为约定。我很好奇这个配置：bootRepackage.enabled=false，我们为什么需要它？
@chenrui bootreapackage.enabled 设置为 false，因为我不需要它，启用后它会给我一个异常“无法重命名依赖的 jar”
这有什么更新吗？我觉得在这里贴一些错误日志会更好。

【解决方案1】：

在我重新安装 java 后它最终开始工作。发现这是环境变量中设置的 JAVA_HOME 冲突的问题。除了 eclipse 导出的战争不支持 gradle 并且在战争中产生战争而不是在战争中产生 gradle 产生的子项目的 jar
