创建JavaFX可执行文件，包括JRE和外部库

Question

我在NetBeans下开发了一个JavaFX应用程序，需要JRE8u60和一些外部库（jar和dll）以及一个“SQLite”数据库文件才能运行。我正在寻找一种方法来创建一个可执行文件或安装程序，它包括（或安装）这个版本的JRE和所需的库。

首先，我尝试了NetBeans本机打包程序，如https://NetBeans.org/kb/docs/java/native_pkg.html#fx所示，但是当我运行获得的安装程序时，可执行文件显示它找不到主类。我只是遵循了教程，所以我不知道我是否错过了适合我的特殊情况的一些必要的点。我的build.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<project name="Petra" default="default" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">
<description>Builds, tests, and runs the project Petra.</description>
<import file="nbproject/build-impl.xml"/>
<target name="-post-jfx-deploy">
   <fx:deploy width="${javafx.run.width}" height="${javafx.run.height}" 
             nativeBundles="all"
             outdir="${basedir}/${dist.dir}" outfile="${application.title}">
      <fx:application name="${application.title}" mainClass="${javafx.main.class}"/>
      <fx:resources>
          <fx:fileset dir="${basedir}/${dist.dir}" includes="Petra.jar"/>
      </fx:resources>
      <fx:info title="${application.title}" vendor="${application.vendor}"/>
      <fx:platform basedir="C:\Program Files\Java\jdk1.8.0_60"/> 
  </fx:deploy>  
</target>
</project>

编译时，输出中似乎没有任何错误：

但是当我运行安装程序时，生成的“exe”抛出两个窗口：

有线索吗？？

Answer 1

我还没有找到将JRE直接放入可执行文件的方法，但这里有一种方法至少可以将所有库放入Jar（使用Netbeans）以减少混乱。您以前可能在StackOverflow上的其他地方见过它。

1. 清理并生成程序。
2. 打开文件

将以下代码添加到build.xml：

<target name="package-for-store" depends="jar">

    <property name="store.jar.name" value="MyJarName"/>

    <!-- don't edit below this line -->

    <property name="store.dir" value="store"/>
    <property name="store.jar" value="${store.dir}/${store.jar.name}.jar"/>

    <echo message="Packaging ${application.title} into a single JAR at ${store.jar}"/>

    <delete dir="${store.dir}"/>
    <mkdir dir="${store.dir}"/>

    <jar destfile="${store.dir}/temp_final.jar" filesetmanifest="skip">
        <zipgroupfileset dir="dist" includes="*.jar"/>
        <zipgroupfileset dir="dist/lib" includes="*.jar"/>

        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
        </manifest>
    </jar>

    <zip destfile="${store.jar}">
        <zipfileset src="${store.dir}/temp_final.jar"
        excludes="META-INF/*.SF, META-INF/*.DSA, META-INF/*.RSA"/>
    </zip>

    <delete file="${store.dir}/temp_final.jar"/>

</target>

只需将MyJarName更改为您希望调用的Jar文件（省略.Jar扩展名）。
