为什么Bitbucket无法构建我的JFX项目？

Question

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

该@BeforeClass运行JFXPanel:

@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.

Answer 1

Bitbucket仅提供headless test environment无图形显示.您会收到异常,java.lang.UnsupportedOperationException: Unable to open DISPLAY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严重依赖的版本OpenJDK和OpenJFX.有时您必须应用补丁Monocle才能使其正常工作.请参阅OpenJFX wiki - Monocle和Github - Monocle.

有关详细信息,请参阅JEROME'S BLOG - 在无头模式下测试JavaFX和/或使用TestFX和JavaFX 8测试Uwe的博客 - 无头UI测试.
