使用Bitbucket管道构建JavaFx应用程序 [英] Building JavaFx application using Bitbucket pipelines

问题描述

我正在尝试使用bitbucket管道构建JavaFx项目.为此，我正在使用maven:3-jdk-8 docker image.此Docker映像使用OpenJDK 8而不是Oracle的OpenJDK 8(由于许可证问题)，其中不包括JavaFx部分.请注意，我必须使用Java 8来构建我的项目！ 我遇到的问题是我无法仅使用该docker映像来构建应用程序.

I am trying to build JavaFx project using bitbucket pipelines. For that I am using maven:3-jdk-8 docker image. This Docker image uses OpenJDK 8 instead of Oracle's one (due to the lincensing issue) which does not include the JavaFx part. Note that I have to use Java 8 to build my project! Problem that I am getting is that I am not able to build the application using that docker image alone.

根据对同一问题的回答中提出的建议( https://stackoverflow.com/a/40167253/2000338 ): 我尝试使用此bitbucket-pipelines.yml尝试克服这种情况:

As proposed in an answer to the same question (https://stackoverflow.com/a/40167253/2000338): I tried using this bitbucket-pipelines.yml to try to overcome the situation:

image: maven:3-jdk-8

pipelines:
  default:
    - step:
        script: # Modify the commands below to build your repository.
          - apt-get update
          - apt-get install -y openjfx
          - mvn clean install # -B batch mode makes Maven less verbose

在步骤2中，似乎已正确安装了openjfx. 但是在步骤3中，我收到以下错误消息:

In step 2 it seems that openjfx is installed properly. But in step 3 I am getting following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project ***********: Compilation failure: Compilation failure: 
[ERROR] /opt/atlassian/pipelines/agent/build/src/main/java/********/******/****/MainFx.java:[7,26] package javafx.application does not exist

它似乎仍然在抱怨缺少JavaFx库，但是我不知道为什么. 在开发人员机器上(Windows 7，jdk1.8.0_221)，我可以执行maven构建，而不会出现问题.

It seams that it is still complaining on the JavaFx libraries missing, but I am not aware of why. On my developer machine (Windows 7, jdk1.8.0_221) I can execute maven build without an issue.

推荐答案

以前的方法缺少的是javafx库不在类路径中.基本上为了使Maven构建工作，我必须将jfxrt.jar添加到类路径中. 我发现在安装javafx之后的maven:3-jdk-8映像中，可以在以下位置找到该库: /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar

What was missing in previous approach is that the javafx library was not on the classpath. Basically in order to make maven build work I had to add the jfxrt.jar to the classpath. I found that in the maven:3-jdk-8 image after installing javafx the library can be found in: /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar

在构建过程中将此文件添加到类路径中即可解决问题.

Adding this file to a classpath during build run will do the trick.

(对我有用)的一个想法是将该库作为system范围包含在应用程序pom/dependecy部分中.

One idea (that worked for me) is to include this library in application pom/dependecy part as a system scope.

就我而言，我为此做了一个Maven个人资料:

In my case I made a maven profile for that:

    <profiles>
    <profile>
        <id>docker_build</id>
        <activation>
            <activeByDefault>false</activeByDefault>
        </activation>
        <dependencies>
            <dependency>
                <groupId>com.oracle</groupId>
                <artifactId>javaFX</artifactId>
                <version>2.2</version>
                <scope>system</scope>
                <systemPath>${javafx-location}</systemPath>
            </dependency>
        </dependencies>
    </profile>
</profiles>

要运行此Maven构建，必须发出适当的maven命令以添加此配置文件.例如.

In order to run this maven build you have to issue proper maven command to add this profile. E.g.

mvn clean install -P docker_build -Djavafx-location=/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar

为简化此操作，我使用以下Dockerfile制作了Docker映像:

To simplify this I made a Docker image using following Dockerfile:

FROM maven:3-jdk-8
RUN apt-get update && \
    apt-get install -y --no-install-recommends openjfx
COPY settings.xml /root/.m2/

使用以下maven settings.xml文件:

which uses following maven settings.xml file:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
    <localRepository>/usr/share/maven/ref/repository</localRepository>
    <activeProfiles>
        <activeProfile>docker_build</activeProfile>
    </activeProfiles>
    <profiles>
        <profile>
            <id>docker_build</id>
        <properties>
            <javafx-location>/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar</javafx-location>
        </properties>
        </profile>
    </profiles>
</settings>

如果有人发现它有用，我也将其发布到了Docker中心: https://hub.docker.com/r/brzigonzales/maven-javafx

I also published it to the Docker hub if somebody may find it useful: https://hub.docker.com/r/brzigonzales/maven-javafx
