我正在开发一个依赖于JFX实例运行的单元测试，但是当Bitbucket执行测试时，它在初始化JFXPanel时失败。
这是我的bitbucket管道：
pipelines:
default:
- step:
caches:
- maven
script: # Modify the commands below to build your repository.
- apt-get update && apt-get install -y openjfx
- mvn install:install-file -Dfile=lib/builder.jar -DgroupId=builder -DartifactId=builder
-Dversion=1.0 -Dpackaging=jar
- mvn clean test
运行JFXPanel的@BeforeClass：
@BeforeClass
public static void setup() {
new JFXPanel();
}
我可以在我的计算机上构建我的项目没有问题，但Bitbucket不能。

我找不到有同样问题的人。像bitbucket上的构建失败的类似问题表明它可能是缺少某些命令的管道。
Bitbucket只提供没有图形显示的headless test environment。您将获得java.lang.UnsupportedOperationException: Unable to open DISPLAY异常，因为JavaFX默认情况下不支持无头环境。
您必须安装和配置JavaFX的Glass窗口组件的无头实现，如OpenJFX的Monocle项目。 Monocle严重依赖于OpenJDK和OpenJFX的版本。有时您必须将补丁应用于Monocle才能使其正常工作。见OpenJFX wiki - Monocle和Github - Monocle。
有关详细信息，请参阅JEROME'S BLOG - Testing JavaFX in headless mode和/或Uwe's Blog - Headless UI Testing with TestFX and JavaFX 8。
