使用ANT编译的JavaFX code [英] Compile JavaFX Code using ANT
问题描述
我有以下安装在我的系统上 -
Java版本1.7.0_09

当我试图编译code。使用ANT它显示我的错误信息 -

的更新的Java 8 的
在甲骨文的Java 8， jfxrt.jar 默认情况下在类路径上，所以你并不需要在此说明，明确其添加到类路径回答。添加 jfxrt.jar 到classpath中，只需要对Java 7。
编制问题，是因为 jfxrt.jar 从的jre \\ lib中并没有在classpath中设置。
该错误的taskdef是因为路径指定蚂蚁javafx.jar 值不指向一个有效文件，在文件系统造成的。
我想可能还有各地使用问题的：而非; 在分隔条件路径和使用 / ，而不是 \\ 来指定路径，但蚂蚁似乎pretty宽容那些事情，所以他们可能不要T在所有问题。
示例项目所得到的应用程序是使用执行
的java -classpathC：\\ Program Files文件（x86）的\\的Java \\ jdk1.7.0_09 \\ JRE \\ lib目录\\ jfxrt.jar; XYZ \\ lib目录\\ ScenicView.jar; XYZ \\建立\\ XYZ交友
请注意，该样品在构建脚本是很基本的，其实只是提供作为首发脚本，让你去。你是最好的关闭也将进一步部署任务 Ant任务（像 FX：部署），以确保正确的打包应用程序支持像一个点击即可运行罐子功能。如果不是这样，或者使用NetBeans，让它产生合适的Ant构建文件给你。
修改后的Ant脚本我用来建立（与蚂蚁1.8.4 ）示例应用程序我挂的是：
＆LT;项目名称=XYZ默认值=XYZBASEDIR =XYZ的xmlns：FX =JavaFX的：com.sun.javafx.tools.ant＆GT;

I have following installed on my system -
Java version "1.7.0_09"
JavaFX 2.0 SDK
NetBeans 7.2.1
When I am trying to compile the code using ANT it showing me error message -
Could not load definitions from resource com/sun/javafx/tools/ant/antlib.xml. It could not be found.
Build.XML contains
<project name="XYZ" default="XYZ" basedir="XYZ" xmlns:fx="javafx:com.sun.javafx.tools.ant">

Update for Java 8
In Oracle Java 8, jfxrt.jar is on the class path by default, so you don't need to explicitly add it to the class path as described in this answer. Adding jfxrt.jar to the classpath is only necessary for Java 7.
The compilation problem was because jfxrt.jar from jre\lib was not set in the classpath.
The taskdef error was caused because the path specified to ant-javafx.jar value does not point to a valid file on your filesystem.
I thought there might also be issues around using a : rather than a ; in seperating paths and in using / rather than \ to specify paths, but ant seems pretty forgiving about those things, so they likely don't matter at all.
I created a sample project based on a very slightly modified version of your build script which worked for me (no taskdef warning and no compilation errors). It is set up for jdku9 windows 64bit. If you are using a different version of the jdk, you will need to adjust the paths in the script appropriately. Check which bit version of the jdk you have installed - if it is 64 bit then you use C:\Program Files\Java\..., if it is 32 bit then you use C:\Program Files (x86)\Java\...
The resultant application for the sample project is executable using:
java -classpath "c:\Program Files (x86)\Java\jdk1.7.0_09\jre\lib\jfxrt.jar;XYZ\lib\ScenicView.jar;XYZ\build\XYZ" FriendFinder
Note that the build script in the sample is very basic and is really just provided as a starter script to get you going. You are best off also adding ant tasks for further deployment tasks (like fx:deploy) to ensure a properly packaged application which supports features like a click-to-run jar. Either that, or use NetBeans and let it generate appropriate ant build files for you.
The modified ant script I used to build (with ant 1.8.4) the sample application I linked is:
<project name="XYZ" default="XYZ" basedir="XYZ" xmlns:fx="javafx:com.sun.javafx.tools.ant">
<property name="srcXYZ" location="src/XYZ"/>
<property name="buildXYZ" location="build/XYZ"/>
<property name="classpath" location="C:\Program Files (x86)\Java\jdk1.7.0_09\jre\lib\jfxrt.jar;lib\ScenicView.jar"/>
<target name="init">
<tstamp/>
<mkdir dir="${buildXYZ}"/>
</target>
<target name="XYZ" depends="init">
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
uri="javafx:com.sun.javafx.tools.ant" classpath=".:C:\Program Files (x86)\Java\jdk1.7.0_09\lib\ant-javafx.jar"/>
<javac includeantruntime="false" classpath="${classpath}" srcdir="${srcXYZ}" destdir="${buildXYZ}"/>
</target>
</project>
