我是 xml 新手，并尝试部署我的 javafx 程序，开始运行和清理我有以下错误，并且找不到有关其解决方案的任何答案，所以如果你帮助我将不胜感激：
F:\IT\PROGRAMMING\LJPROJECTS\MyShutDownTheCompProgram\build.xml:67：XML 文档结构必须在同一个实体内开始和结束。
xml代码如下：
<?xml version="1.0" encoding="UTF-8"?><!-- You may freely edit this file. See commented blocks below for --><!-- some examples of how to customize the build. --><!-- (If you delete it and reopen the project it will be recreated.) --><!-- By default, only the Clean and Build commands use this build script. --><project name="MyShutDownTheCompProgram" default="default" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">
<description>Builds, tests, and runs the project MyShutDownTheCompProgram.</description>
<import file="nbproject/build-impl.xml"/>
<!--
There exist several targets which are by default empty and which can be
used for execution of your tasks. These targets are usually executed
before and after some main targets. Those of them relevant for JavaFX project are:
-pre-init: called before initialization of project properties
-post-init: called after initialization of project properties
-pre-compile: called before javac compilation
-post-compile: called after javac compilation
-pre-compile-test: called before javac compilation of JUnit tests
-post-compile-test: called after javac compilation of JUnit tests
-pre-jfx-jar: called before FX SDK specific <fx:jar> task
-post-jfx-jar: called after FX SDK specific <fx:jar> task
-pre-jfx-deploy: called before FX SDK specific <fx:deploy> task
-post-jfx-deploy: called after FX SDK specific <fx:deploy> task
-pre-jfx-native: called just after -pre-jfx-deploy if <fx:deploy> runs in native packaging mode
-post-jfx-native: called just after -post-jfx-deploy if <fx:deploy> runs in native packaging mode
-post-clean: called after cleaning build products
(Targets beginning with '-' are not intended to be called on their own.)
Example of inserting a HTML postprocessor after javaFX SDK deployment:
<target name="-post-jfx-deploy">
<basename property="jfx.deployment.base" file="${jfx.deployment.jar}" suffix=".jar"/>
<property name="jfx.deployment.html" location="${jfx.deployment.dir}${file.separator}${jfx.deployment.base}.html"/>
<custompostprocess>
<fileset dir="${jfx.deployment.html}"/>
</custompostprocess>
</target>
Example of calling an Ant task from JavaFX SDK. Note that access to JavaFX SDK Ant tasks must be
initialized; to ensure this is done add the dependence on -check-jfx-sdk-version target:
<target name="-post-jfx-jar" depends="-check-jfx-sdk-version">
<echo message="Calling jar task from JavaFX SDK"/>
<fx:jar ...>
...
</fx:jar>
</target>
For more details about JavaFX SDK Ant tasks go to
http://docs.oracle.com/javafx/2/deployment/jfxpub-deployment.htm
For list of available properties check the files
nbproject/build-impl.xml and nbproject/jfx-impl.xml.
