Gradle:无法获取主类的未知属性"classesDir" [英] Gradle: Could not get unknown property 'classesDir' for main classes

问题描述

根据文档，我尝试使用Aspectj插件.

According to the documentation, I've tried to use aspectj plugin.

这是我在构建项目时收到的消息.

This is the message I get when I build my project.

FAILURE: Build failed with an exception.

* Where:
Build file '/home/jesudi/projects/gradle-vscode/build.gradle' line: 22

* What went wrong:
A problem occurred evaluating root project 'security'.
> Failed to apply plugin [id 'aspectj.gradle']
   > Could not create task ':compileAspect'.
      > Could not get unknown property 'classesDir' for main classes of type org.gradle.api.internal.tasks.DefaultSourceSetOutput.

这是我的脚本:

buildscript {
    repositories {
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "org.apache.meecrowave:meecrowave-gradle-plugin:1.2.6"
        classpath "gradle.plugin.aspectj:gradle-aspectj:0.1.6"
    }
}

plugins {
    id 'java'
}

project.ext {
    aspectjVersion = '1.9.2'
}

apply plugin: 'aspectj.gradle'
apply plugin: "org.apache.microwave.microwave"

java {
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

dependencies {
    compile("org.apache.meecrowave:meecrowave-core:1.2.6")
    compile("org.apache.meecrowave:meecrowave-specs-api:1.2.6")
}

meecrowave {
    httpPort = 9090
    // most of the meecrowave core configuration
}

这是 gradle -version 输出:

推荐答案

在Gradle 5.x中，此属性已从 classesDir 重命名为 classesDirs .

In Gradle 5.x, this property has been renamed to classesDirs from classesDir.
