JavaFX 和 JFoenix 的 java.lang.IllegalAccessError

Question

我正在尝试在 Scene Builder 中使用JFoenix库。
这是我到目前为止：

我添加了 Maven 依赖项：

    <dependency>
        <groupId>com.jfoenix</groupId>
        <artifactId>jfoenix</artifactId>
        <version>9.0.8</version>
    </dependency>

和JFoenix jar到 Scene Builder。

新插件已成功添加到我的库中：

当我现在将一个JFXButton拖到我的场景中时，我可以编译它。
但是当我拖动一个更复杂的项目（例如JFXTabPane并尝试编译它时，我收到以下错误：

如此处所述： https : //github.com/jfoenixadmin/JFoenix/issues/889#issuecomment-450744122

我已经添加了

--module-path=/home/user/javafx-sdk-12.0.1/lib
--add-modules=javafx.base, javafx.controls, javafx.fxml, javafx.graphics, javafx.media, javafx.swing, javafx.web
--add-opens
javafx.base/com.sun.javafx.runtime=ALL-UNNAMED
--add-opens
javafx.controls/com.sun.javafx.scene.control.behavior=ALL-UNNAMED
--add-opens
javafx.controls/com.sun.javafx.scene.control=ALL-UNNAMED
--add-opens
javafx.base/com.sun.javafx.binding=ALL-UNNAMED
--add-opens
javafx.base/com.sun.javafx.event=ALL-UNNAMED
--add-opens
javafx.graphics/com.sun.javafx.stage=ALL-UNNAMED

但它没有帮助。

我的工具：

• 爪哇 12
• 网豆 12
• JavaFX 12
• 场景生成器 11

更新：

奇怪的是，Netbeans 将我的一些 VM 选项电影到参数栏中：

Answer 1

尽管 JFoenix 9.0.8 和 Java 12 存在问题（在JFXTextField等某些组件中使用 unsafe ），但此问题不会阻止使用 Java 和 JavaFX 12.0.1 运行JFXTabPane组件。

基于这个helloFX示例，我编辑了它的 FXML 文件以包含一个带有一个选项卡的JFXTabPane ：

pom 看起来像：

<dependencies>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>12.0.1</version>
    </dependency>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-fxml</artifactId>
        <version>12.0.1</version>
    </dependency>
    <dependency>
        <groupId>com.jfoenix</groupId>
        <artifactId>jfoenix</artifactId>
        <version>9.0.8</version>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <release>12</release>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.2</version>
            <configuration>
                <mainClass>org.openjfx.App</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>

但是，当运行mvn clean javafx:run我得到异常报告：

Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin \
    (in module com.jfoenix) cannot access class com.sun.javafx.scene.control.behavior.TabPaneBehavior \ 
    (in module javafx.controls) because module javafx.controls \
    does not export com.sun.javafx.scene.control.behavior to module com.jfoenix

所以按照建议，我将修改javafx-maven-plugin以避免它：

<configuration>
    <mainClass>org.openjfx.App</mainClass>
    <options>
        <option>--add-opens</option>
        <option>javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix</option>
    </options>
</configuration>

现在运行mvn clean javafx:run我得到一个新的异常：

Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin$TabHeaderContainer (in module com.jfoenix) \
    cannot access class com.sun.javafx.scene.control.LambdaMultiplePropertyChangeListenerHandler \ 
    (in module javafx.controls) because \
    module javafx.controls does not export com.sun.javafx.scene.control to module com.jfoenix

所以我们将这个新选项添加​​到插件中：

<configuration>
    <mainClass>org.openjfx.App</mainClass>
    <options>
        <option>--add-opens</option>
        <option>javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix</option>
        <option>--add-opens</option>
        <option>javafx.controls/com.sun.javafx.scene.control=com.jfoenix</option>
    </options>
</configuration>

最后， mvn clean javafx:run工作正常：

请注意，如果您不使用该插件，您也可以在命令行中运行，例如：

java \
--add-opens javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix \
--add-opens javafx.controls/com.sun.javafx.scene.control=com.jfoenix \
--module-path /Users/user/.m2/repository/com/jfoenix/jfoenix/9.0.8/jfoenix-9.0.8.jar:\
    /Users/user/javafx-sdk-12.0.1/lib \
--add-modules com.jfoenix,javafx.controls,javafx.fxml \
-classpath hellofx/target/classes \
org.openjfx.App

如果您检查此命令行，您会注意到您的--add-modules缺少com.jfoenix模块，这将解释为什么您的“--add-opens”不起作用。
