Gradle不包括FXML和图像 [英] Gradle not including FXML and images

问题描述

我一直在寻找在 build.gradle 中包含FXML和图像的正确方法，以便将它们构建到jar中。我在此处进行了尝试，但仍然无法正常工作。

I have been looking around for the proper way to include FXML and images in the build.gradle so that they are build into the jar. I have look here and tried it but it still does not work.

抛出此错误： java.lang.NullPointerException：inputStream为null。

这是 build.gradle （ Github ）：

group 'com.voidustries'
version '1.0-SNAPSHOT'

sourceSets {
    main {
        resources {
            srcDirs = ["src/main/java/com/voidustries/poly"]
            includes = ["gui/layoutForm.fxml"]
        }
    }
}

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.1.0'
    }
}

apply plugin: 'java'
apply plugin: 'org.junit.platform.gradle.plugin'

repositories {
    mavenCentral()
}

dependencies {
    testCompile('org.junit.jupiter:junit-jupiter-api:5.1.0')
    testRuntime('org.junit.jupiter:junit-jupiter-engine:5.1.0')
}

task wrapper(type: Wrapper) {
    description = 'Generates gradlew[.bat] scripts'
    gradleVersion = '4.3.1'
}

test {
    testLogging {
        events "passed", "skipped", "failed"
    }
}

这是GUI.java（ Github ）：

Here is GUI.java (Github):

FXMLLoader loader = new FXMLLoader();
FileInputStream fis = new FileInputStream(settings);
ResourceBundle resourceBundle = new PropertyResourceBundle(fis);
loader.setResources(resourceBundle);

Parent root = loader.load(getClass().getResourceAsStream("layoutForm.fxml"));
Platform.setImplicitExit(false);

stacktrace表示 loader.load（getClass（）。getResourceAsStream（ layoutForm.fxml））; 导致错误

The stacktrace says that loader.load(getClass().getResourceAsStream("layoutForm.fxml")); is causing the error

这是源代码树：

com
└───voidustries
    └───poly
        │   CustomFormatter.java
        │   Main.java
        │   PolyThreads.java
        │   SysTray.java
        │
        ├───gui
        │       Controller.java
        │       GUI.java
        │       Icon.png
        │       layoutForm.fxml
        │
        └───img
                Icon.png

您会看到 layoutForm.fxml 和 Icon.png 都在那里在树上

you can see that layoutForm.fxml and Icon.png are both there in the tree

这是外面的树：

com
└───voidustries
    └───poly
        │   CustomFormatter.class
        │   Main.class
        │   PolyThreads.class
        │   SysTray.class
        │
        └───gui
                Controller.class
                GUI.class

在外面的树上，他们都不存在，我已经花了好几个小时试图解决这个问题。任何帮助将不胜感激。

In the out tree they are both absent and I have been fiddling for hours trying to fix this issue. Any help would be greatly appreciated.

此外，如果您需要更多此处是Github存储库

Also if you need more here is the Github repository

推荐答案

您正在放置xml文件在名为 src / main / java 的文件夹中（提示：Java目录适用于Java文件）

You are putting xml files in a folder called src/main/java (hint: java dir is for java files)

资源（例如xml，图像文件等）应该放在 src / main / resources

Resources (eg xml, image files etc) should go in src/main/resources

Maven和Gradle。如果您想更改默认值，则可以，但是我强烈建议您考虑遵循明智的约定。

This is a standard convention followed by both Maven and Gradle. If you want to change the defaults you can, but first I strongly advise you consider following the sensible conventions.

此外，有关类加载器的说明

Also, a note on classloaders

• SomeClass.class.getResource（ foo.xml）将查找相对于类包的xml


• SomeClass。 class.getResource（ / foo.xml）将查找相对于类路径根的xml

在您的示例中

getClass().getResourceAsStream("layoutForm.fxml")

这是在类路径 com / voidustries / poly / gui / layoutForm.fxml

因此，如果要将资源保留在原处，则需要将 src / main / java 添加到资源文件夹中，而不是 src / main / java / com / voidustries / poly

So if you want to leave your resources where they are, you will want to add src/main/java to the resource folders, not src/main/java/com/voidustries/poly
