When I try to run ./gradlew run, I am getting the following error...

> Task :run FAILED
Error: Could not find or load main class com.liljaw.desktop.CliTestApp
Caused by: java.lang.ClassNotFoundException: com.liljaw.desktop.CliTestApp

我的梯度项目是一个多模块建设,定义如下......

建设。梯度

plugins {
    id  application 
}

allprojects {
    group  com.liljaw 
}

subprojects {
    apply plugin:  java 

    sourceCompatibility = 1.8
}

project( :desktop ) {
    dependencies {
        implementation project( :core )
    }
}

application {
    mainClass =  com.liljaw.desktop.CliTestApp 
}

情况。梯度

rootProject.name =  LilJaw 
include  core 
include  desktop

主要项目下的桌面文件结构如下......

desktop
├── run.sh
└── src
    └── main
        └── java
            └── com
                └── liljaw
                    └── desktop
                        ├── CliTestApp.java
                        ├── JavaLogInterface.java
                        ├── PcmFloatPlayer.java
                        └── SourceDataLineTest.java

究竟是什么错了,因此我无法从终点站接手申请?

Answer 1

我改变了你根基项目的范围。

allprojects {
    group  com.liljaw 
}

subprojects {
    apply plugin:  java 

    sourceCompatibility = 1.8
}

project( :desktop ) {

    apply plugin:  application 

    dependencies {
        implementation project( :core )
    }
    application {
        mainClass =  com.liljaw.desktop.CliTestApp 
    }
}

问题在于,您需要有一些应用的缩略语application至desktop。项目<代码>。

还应当为<代码>desktop 界定<>>>>>> 申请编号。项目2 项目。

在你的情况下,它研究的是根本项目的主要地图集,并且失败。

能够使用<条码>梯度-p desktop/条码”的Im 可在以下屏幕上运行。

Answer 2

You should try with adding mainClassName = <your main class with full package path. You can get the details as mentioned here

希望会有所助益。

<>Update:

I tried running the same set of code as yours, and it worked like a charm. Here are things I have : Project Structure

这里正在建设。梯度:

plugins {
    id  application 
}

allprojects {
    group  com.adking 
}

subprojects {
    apply plugin:  java 

    sourceCompatibility = 1.8
}

project( :desktop ) {
    dependencies {
        implementation project( :core )
    }
}

application {
    mainClass =  com.adking.desktop.CliTestApp 
}

和背景。梯度

rootProject.name =  LilJaw 
include  core 
include  desktop

On Executing the command ./gradle run Got result as:


> Task :run
Connected to main

BUILD SUCCESSFUL in 1s
3 actionable tasks: 2 executed, 1 up-to-date

因此,我同意,主要地图册实际上并不必要。
