我无法使用netbeans 11和JavaFX12调试应用程序

Question

我已经下载了支持Java12的netbeans 11，因此我使用maven>https://openjfx.io/openjfx-docs/#下一个步骤从运行JavaFX和netbeans非模块化的Gluon网页继续执行步骤

我已经按照说明中所示配置了运行这个应用程序的操作。

运行Project clean javafx：Run

Answer 1

如果您看到javafx-maven-plugin的文档，您可以向run目标添加一些VM参数，以便在NetBeans中调试项目。

但是，为了使通常的run目标准备好只运行项目而不调试，而不注释掉添加的选项，我们可以向插件添加第二次执行。

这样修改你的插件：

<plugin>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>0.0.2</version>
    <executions>
        <execution>
            <!-- Default configuration for running -->
            <id>default-cli</id>
            <configuration>
                <mainClass>com.mycompany.simonsaysgfx.App</mainClass>
            </configuration>
        </execution>
        <execution>
            <!-- Configuration for debugging -->
            <id>debug</id>
            <configuration>
                <options>
                    <option>-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:8000</option>
                </options>
                <mainClass>com.mycompany.simonsaysgfx.App</mainClass>
            </configuration>
        </execution>
    </executions>
</plugin>

mvn clean javafx:run

以正常运行应用程序，并且：

mvn clean javafx:run@debug

若要启动调试模式，请执行以下操作。然后您将看到如下内容：

[INFO] --- javafx-maven-plugin:0.0.2:run (debug) @ Project ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 1 resource
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 3 source files to /path/to/project/target/classes
Listening for transport dt_socket at address: 8000

此时，您需要设置断点，并将NetBeans->Debug->AttachDebugger中的调试器附加到端口8000：

<?xml version="1.0" encoding="UTF-8"?>
