GetResource 方法在 Java 11 中不起作用

Question

This is my project structure:

This is my module-info:

open module org.client.main {
    exports org.apj.client.app;
    requires javafx.controls;
    requires javafx.base;
    requires javafx.fxml;
    requires spring.context;
    requires spring.web;
    requires java.sql;
    requires spring.beans;
    requires spring.core;
}

This is my parent gradle build file:

subprojects {
    afterEvaluate {
        repositories {
            jcenter()
        }

        compileJava {
            doFirst {
                options.compilerArgs = [
                        '--module-path', classpath.asPath,
                ]
                classpath = files()
            }
        }

        compileTestJava {
            inputs.property("moduleName", moduleName)
            doFirst {
                options.compilerArgs = [
                        '--module-path', classpath.asPath,
                        '--add-modules', 'junit',
                        '--add-reads', "$moduleName=junit",
                        '--patch-module', "$moduleName=" + files(sourceSets.test.java.srcDirs).asPath,
                ]
                classpath = files()
            }
        }

        test {
            inputs.property("moduleName", moduleName)
            doFirst {
                jvmArgs = [
                        '--module-path', classpath.asPath,
                        '--add-modules', 'ALL-MODULE-PATH',
                        '--add-reads', "$moduleName=junit",
                        '--patch-module', "$moduleName=" + files(sourceSets.test.java.outputDir).asPath,
                ]
                classpath = files()
            }
        }
    }
}

This is my client module build file:

plugins {
    id 'java'
}

group 'APJ'
version '1.0-SNAPSHOT'

sourceCompatibility = 11

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.springframework', name: 'spring-webmvc', version: '5.1.4.RELEASE'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

ext.moduleName = 'org.client.main'

I am trying to getResource for FXMLLoader but I simply can not get it to work. I have been struggling for 2 hours and I am really desperate right now. I have tried like every possible combination of file name, every possible location but still it is returning null.

Also I have tried ClassLoader.getSystemClassLoader().getResource("/login.fxml") getClass().getResource("/login.fxml") But it is also not working.

Can someone help me with this ? I would be very grateful.

Answer 1

I noticed with Java 11, 2 options to make getResource work:

1. use plugin 'org.openjfx.javafxplugin' version '0.0.7' or

2. use '--patch-module' in the link provided by Slaw above: Where do resource files go in a Gradle project that builds a Java 9 module?

    run { doFirst { jvmArgs = [ '--module-path', classpath.asPath, '--patch-module', "$moduleName=" + files(sourceSets.main.output.resourcesDir).asPath, '--module', mainClassName ] } }

Answer 2

So I have solved my issue by using java.io.File . Firstly I have created new File and checked where it is being saved. Then, since I have now known the root I have found my path to my resource and created a new File object - File myFile = new File("path_to_my_resource") . Then I got URL using toURI and toURL methods - myFile.toURI().toURL() .

This is definitely hack but if someone is struggling like I was it can be used as a quick fix.
