Question

我遇到的问题是Java能够找到我的主要类LibGDX游戏。我正和其他人一起工作，所有人都能正确设置项目并在他们的计算机上运行/构建游戏。

项目结构类似于：

love-pirates
    core
        src
            com.pirates.game
                LovePirates.java
    desktop
        src
            com.pirates.game.desktop
                DesktopLauncher.java

当我尝试运行DesktopLauncher.java时，我得到：

Exception in thread "main" java.lang.ClassNotFoundException: com.pirates.game.desktop.DesktopLauncher

当我尝试通过Gradle构建时，我得到：

error: cannot find symbol 
import com.pirates.game.LovePirates;
                       ^
symbol:   class LovePirates
location: package com.pirates.game

这是桌面模块中的build.gradle：

apply plugin: "java"

sourceCompatibility = 1.8
sourceSets.main.java.srcDirs = [ "src/" ]

project.ext.mainClassName = "com.pirates.game.desktop.DesktopLauncher"
project.ext.assetsDir = new File("../android/assets");

task run(dependsOn: classes, type: JavaExec) {
    main = project.mainClassName
    classpath = sourceSets.main.runtimeClasspath
    standardInput = System.in
    workingDir = project.assetsDir
    ignoreExitValue = true
}

task dist(type: Jar) {
    from files(sourceSets.main.output.classesDir)
    from files(sourceSets.main.output.resourcesDir)
    from {configurations.compile.collect {zipTree(it)}}
    from files(project.assetsDir);

    manifest {
        attributes 'Main-Class': project.mainClassName
    }
}

dist.dependsOn classes

eclipse {
    project {
        name = appName + "-desktop"
        linkedResource name: 'assets', type: '2', location: 'PARENT-1-PROJECT_LOC/android/assets'
    }
}

task afterEclipseImport(description: "Post processing after project generation", group: "IDE") {
  doLast {
    def classpath = new XmlParser().parse(file(".classpath"))
    new Node(classpath, "classpathentry", [ kind: 'src', path: 'assets' ]);
    def writer = new FileWriter(file(".classpath"))
    def printer = new XmlNodePrinter(new PrintWriter(writer))
    printer.setPreserveWhitespace(true)
    printer.print(classpath)
  }
}

我的核心模块中的build.gradle：

apply plugin: "java"

sourceCompatibility = 1.8
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

sourceSets.main.java.srcDirs = [ "src/" ]


eclipse.project {
    name = appName + "-core"
}

即使我作为JAR导出并尝试在另一台机器上运行它，我也会找不到主类。所以它有时可以编译完成（0个警告，0个错误），但是没有正确运行。

我正在使用jdk 1.8.0_65在OSX上使用IntelliJ IDEA 15。我很乐意提供更多所需信息。非常感谢任何帮助！

编辑0：以下是我编译的DesktopLauncher的路径：

love-pirates/desktop/build/classes/main/com/pirates/game/desktop/DesktopLauncher.class

找不到主类
