Question

我有以下简单的build.gradle文件：

apply plugin: 'java'

task foo(type: JavaExec) {
    main = 'gradletest2.Main'
    classpath = runtimeClasspath
}

在执行时会导致产生以下错误：

C:\Users\J\Documents\Development\eclipse-photon\gradletest2>gradle foo

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\J\Documents\Development\eclipse-photon\gradletest2\build.gradle' line: 17

* What went wrong:
A problem occurred evaluating root project 'gradletest2'.
> Could not get unknown property 'runtimeClasspath' for task ':foo' of type org.gradle.api.tasks.JavaExec.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s

BTW Main很简单：

package gradletest2;
public class Main {
    public static void main(String[] args) {       
        System.out.println("gradletest2");
    }
}

为什么会出现此错误？我正在https://youtu.be/OFUEb7pLLXw?t=2043上观看有关YT的官方gradle教程视频，但是很遗憾，它已经很老了，所以我想知道这是否现在是不正确的语法。提前致谢。

我正在使用gradle 4.10.2。

Answer 1

runtimeClasspath是主sourceSet的属性。正确的语法是

classpath = sourceSets.main.runtimeClasspath

gradle：无法获得任务的未知属性“ runtimeClasspath”
