尽管添加了JavaFX插件，Gradle项目仍无法找到JavaFX应用程序类

我对Gradle和JavaFX都是新手。我已经将JavaFX插件添加到我的

build.gradle

following和。但是，我的主类

Library.java

在尝试扩展JavaFX的

应用程序时无法检测到它

build.gradle

plugins {
    // Apply the java-library plugin to add support for Java Library
    id 'java-library'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.8'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

dependencies {
    // This dependency is exported to consumers, that is to say found on their compile classpath.
    api 'org.apache.commons:commons-math3:3.6.1'

    // This dependency is used internally, and not exposed to consumers on their own compile classpath.
    implementation 'com.google.guava:guava:28.0-jre'

    // Use JUnit test framework
    testImplementation 'junit:junit:4.12'
}

jar {
    manifest {
        attributes 'Main-Class': 'Chess.Library'
    }
}

mainClassName = 'Chess.Library'

根本没有来自
javafx
包的
应用程序。我错过了什么

我使用Spring工具套件4.0作为我的IDE，带有Buildship Gradle插件，如果有帮助的话。我也在运行Oracle Java 13

编辑1:

我已经添加了建议的更改，这就是我的build.gradle现在的样子

plugins {
    // Apply the java-library plugin to add support for Java Library
    id 'java-library'
    id 'application'
    id 'org.openjfx.javafxplugin' version '0.0.8'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
    mavenCentral()
}

dependencies {
    // This dependency is exported to consumers, that is to say found on their compile classpath.
    api 'org.apache.commons:commons-math3:3.6.1'

    // This dependency is used internally, and not exposed to consumers on their own compile classpath.
    implementation 'com.google.guava:guava:28.0-jre'

    // Use JUnit test framework
    testImplementation 'junit:junit:4.12'


}

jar {
    manifest {
        attributes 'Main-Class': 'Chess.Library'
    }
}

javafx {
    version = "13"
    modules = [ 'javafx.controls' ]
}

mainClassName = 'Chess.Library'

但问题仍然存在

我还检查了我的项目和外部依赖项，除了
javafx

我自己解决了这个问题，虽然不确定是什么原因造成的，但我的项目的构建路径有一个无限的Java13。修复并重新启动IDE解决了这个问题
