maven - 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。

这是我的位桶管道:

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

@BeforeClass运行 JFXPanel:

@BeforeClass
public static void setup() {
    new JFXPanel();
}

我可以在我的计算机上毫无问题地构建我的项目，但 Bitbucket 不能。

我没有找到有同样问题的人。类似的问题，如在 bitbucket 上构建失败，表示它可能是缺少某些命令的管道。

Answer 1

Bitbucket 仅提供 headless test environment没有图形显示。你得到异常 java.lang.UnsupportedOperationException: Unable to open DISPLAY因为 JavaFX 默认不支持 headless 环境。

您必须安装和配置 JavaFX 的 Glass 窗口组件的 headless 实现，例如 OpenJFX 的 Monocle项目。 Monocle严重依赖 OpenJDK 的版本和 OpenJFX .有时您必须将补丁应用到 Monocle使其工作。见 OpenJFX wiki - Monocle和 Github - Monocle .

如需更多信息，请参阅 JEROME'S BLOG - Testing JavaFX in headless mode和/或 Uwe's Blog - Headless UI Testing with TestFX and JavaFX 8 .
