error: module not found: org.lwjgl.natives in multi-module gradle build

Question

我在尝试运行多模块 gradle 构建时遇到以下错误：

/Users/ashley/Personal/juggernaut/display/src/main/java/module-info.java:2: error: module not found: org.lwjgl.natives
  requires org.lwjgl.natives;
                    ^
/Users/ashley/Personal/juggernaut/display/src/main/java/module-info.java:3: error: module not found: org.lwjgl.glfw.natives
  requires org.lwjgl.glfw.natives;
                         ^
/Users/ashley/Personal/juggernaut/display/src/main/java/module-info.java:4: error: module not found: org.lwjgl.opengl.natives
  requires org.lwjgl.opengl.natives;
                           ^
/Users/ashley/Personal/juggernaut/display/src/main/java/module-info.java:5: error: module not found: org.lwjgl.stb.natives
  requires org.lwjgl.stb.natives;
                        ^
/Users/ashley/Personal/juggernaut/display/src/main/java/module-info.java:6: error: module not found: org.lwjgl.assimp.natives
  requires org.lwjgl.assimp.natives;

我的项目结构如下：

├── build.gradle
├── display
│   ├── build.gradle
│   └── src
│       └── main
│           ├── java
│           │   ├── module-info.java
├── engine
│   ├── build.gradle
│   └── src
│       └── main
│           ├── java
│           │   ├── module-info.java
└── settings.gradle

display 的 module-info.java 需要必要的 LWJGL3 模块：

module uk.ashleybye.juggernaut.display {
  requires org.lwjgl.natives;
  requires org.lwjgl.glfw.natives;
  requires org.lwjgl.opengl.natives;
  requires org.lwjgl.stb.natives;
  requires org.lwjgl.assimp.natives;
  exports uk.ashleybye.juggernaut.display;
}

相关依赖包含在build.gradle:

project.ext.lwjglVersion = "3.2.2"
project.ext.lwjglNatives = "natives-macos"

dependencies {
    implementation "org.lwjgl:lwjgl:$lwjglVersion"
    implementation "org.lwjgl:lwjgl-assimp:$lwjglVersion"
    implementation "org.lwjgl:lwjgl-glfw:$lwjglVersion"
    implementation "org.lwjgl:lwjgl-openal:$lwjglVersion"
    implementation "org.lwjgl:lwjgl-opengl:$lwjglVersion"
    implementation "org.lwjgl:lwjgl-stb:$lwjglVersion"
    runtimeOnly "org.lwjgl:lwjgl:$lwjglVersion:$lwjglNatives"
    runtimeOnly "org.lwjgl:lwjgl-assimp:$lwjglVersion:$lwjglNatives"
    runtimeOnly "org.lwjgl:lwjgl-glfw:$lwjglVersion:$lwjglNatives"
    runtimeOnly "org.lwjgl:lwjgl-openal:$lwjglVersion:$lwjglNatives"
    runtimeOnly "org.lwjgl:lwjgl-opengl:$lwjglVersion:$lwjglNatives"
    runtimeOnly "org.lwjgl:lwjgl-stb:$lwjglVersion:$lwjglNatives"
}

引擎 requires uk.ashleybye.juggernaut.display; 并且有一个实现依赖：implementation project(":display").

我的版本信息：

./gradlew --version                                          Sat 17 Aug 09:31:44 2019

为什么gradle找不到模块？

Answer 1

您的 module-info.class 根本不需要包括任何本地人。

删除每个 requires 中的所有 .natives。

此外，您可以压缩 build.gradle:

["", "-assimp", "-glfw", "-openal", "-opengl", "-stb"].each {
    String base = "org.lwjgl:lwjgl$it:$lwjgl_version"
    implementation base
    runtimeOnly = "$base:natives-$lwjgl_natives"
}

你可以参考我们的this project，它是一个多模块项目，严重依赖lwjgl，也使用了JPMS。
