java - Spring和Gradle构建:无此类属性:类的主类名称:org.gradle.api.internal.project.DefaultProject_Decorated

Question

我有Spring Boot 1.1和1.3项目，偶尔在build.gradle更改期间出现错误

No such property: mainClassName for class:

FAILURE: Build failed with an exception.

• Where: Build file ... line: 43

• What went wrong: A problem occurred evaluating root project '...'.

  No such property: mainClassName for class: org.gradle.api.internal.project.DefaultProject_Decorated



build.gradle


buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url 'https://plugins.gradle.org/m2/'
        }
    }

    dependencies {
        ...
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE' //1.1.7.RELEASE'
        ...
    }
}

// Application Plugins
apply plugin: 'java'
apply plugin: 'spring-boot'


第43行是 mainClassName = 'com....Main'

Answer 1

好吧，我只能说，对于Spring Boot 1.1 gradle插件
mainClassName =可以不使用apply plugin: 'application'
但是对于Spring Boot 1.3，这将是错误的。
因此，Spring Boot 1.1 gradle插件正在应用application_plugin。

我可以看到比较gradle tasks输出，该输出具有由application_plugin定义的任务
