适用于 Mac 的 JavaFX 自包含应用程序打包，无需 JRE [英] JavaFX Self-Contained Application Packaging for Mac without JRE

问题描述

我有一个 JavaFX 8 桌面应用程序，我正在创建一个 .app 应用程序包以将应用程序分发给 Mac 用户.为了减小大小，我创建了一个不包含 JRE 的包(用户必须已经安装了 Java 才能使用生成的包).

I have a JavaFX 8 desktop application and I'm creating an .app application bundle to distribute the application to Mac users. To keep the size down, I create a bundle that doesn't contain the JRE (the user must have Java already installed to use the generated bundle).

我的构建是一个 Gradle 脚本，但由于 Oracle Self-Contained Application Packaging"工具与 Ant 一起工作，我调用 Ant 脚本如下:

My build is a Gradle script but since the Oracle "Self-Contained Application Packaging" tool works with Ant, I make a call out to an Ant script as follows:

ant.importBuild 'mac-bundle-ant.xml'

Ant 脚本本身如下所示:

The Ant script itself then looks like this:

<project name="VocabHunter Packaging" basedir=""
         xmlns:fx="javafx:com.sun.javafx.tools.ant">

    <property environment="env"/>
    <property name="JAVA_HOME" value="${env.JAVA_HOME}"/>

    <target name="jfxbundle" description="Build the application bundle">

        <taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
                 uri="javafx:com.sun.javafx.tools.ant"
                 classpath="${JAVA_HOME}/lib/ant-javafx.jar"/>

        <fx:application id="VocabHunterId"
                        name="VocabHunter"
                        mainClass="io.github.vocabhunter.gui.distribution.PackagedVocabHunter"/>

        <fx:resources id="applicationResourcesId">
            <fx:fileset dir="${basedir}/build/libs"/>
        </fx:resources>

        <fx:deploy outdir="${basedir}/build"
                   nativeBundles="image">

            <fx:platform basedir=""/>

            <fx:application refId="VocabHunterId"/>

            <fx:resources refid="applicationResourcesId"/>

            <fx:info title="VocabHunter">
                <fx:association description="VocabHunter session"
                                extension="wordy"
                                mimetype="application/x-vnd.VocabHunterSession"
                                icon="${basedir}/icons/mac/VocabHunterSession.icns"/>
            </fx:info>

            <fx:bundleArgument arg="icon"
                               value="${basedir}/icons/mac/VocabHunter.icns"/>

        </fx:deploy>

    </target>

</project>

问题是生成的 .app 包不起作用.往里面看，我在 Contents/Java/VocabHunter.cfg 中发现了以下有问题的行:

The problem is that the generated .app bundle does not work. Looking inside, I've found the following problematic line in Contents/Java/VocabHunter.cfg:

app.runtime=$APPDIR/PlugIns/Java.runtime

如果我去掉这一行，那么 .app 包会按预期工作.现在，我已将以下 hack 添加到我的 Gradle 脚本中以解决该问题:

If I get rid of this line then the .app bundle works as expected. For now I've added the following hack to my Gradle script to work around the problem:

jfxbundle.doLast {
    FileTree tree = fileTree(dir: 'build/bundles').include('**/*.cfg')
    tree.each {File file ->
        String content = file.text.replaceAll('(?m)^app\\.runtime=.*$\n', '')
        file.write(content)
    }
}

您可以在此处查看完整代码.

有谁知道如何修复 Ant 脚本从而避免对 Gradle 文件中的 hack 的需要?

Does anyone know how to fix the Ant script and thus avoid the need for the hack in the Gradle file?

为了完整起见，我使用的是适用于 Mac 的 Oracle JDK 1.8.0_66.

In the interests of completeness, I'm using the Oracle JDK 1.8.0_66 for Mac.

推荐答案

这个 bug 从 java 1.8.0 update 60 开始存在，我已经报告了这个，但还不是正式的 bug.

This bug starts to exist from java 1.8.0 update 60, I already reported this but it's not a official bug yet.

问题是内部打包器现在使用INI-file-format，你可以看到我的发现.

The problem is the internal packager using INI-file-format now, you can see my findings here.

您应该能够将捆绑参数launcher-cfg-format"设置为prop"值(喜欢这里)

You should be able to set the bundle-argument "launcher-cfg-format" with the value "prop" (like here)

免责声明:我是 javafx-maven-plugin 的维护者......并且不使用 gradle，但就我所见，应该添加:

disclaimer: I'm the maintainer of the javafx-maven-plugin ... and dont use gradle, but this should be added as far as I can see:

        <fx:bundleArgument arg="launcher-cfg-format" value="prop"/>
