Question

我开发了一个JavaFX应用程序，我部署为.exe，当我在我的电脑上安装时，一切正常。但在我将.exe安装到另一台计算机并尝试打开应用程序后，它显示错误：

由于主要类别的异常而失败。

有人可以帮我解决这个错误吗？

build.fxml

    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>

    nbproject/build-impl.xml and nbproject/jfx-impl.xml.

我也尝试将build.fxml更改为此但仍然相同：

Answer 1

您在构建时是否使用了任何VM参数？搜索错误时会显示此SE帖子：JavaFX failed due to exception in main class。

尝试从控制台运行可执行文件和jar，以进行调试：

有什么例外？尝试从控制台运行可执行文件，并尝试使用java -jar从控制台运行可执行jar。并将结果作为问题的一部分发布。

running from console

Answer 2

这是java问题。如果您没有将java添加到您的exe包中，那么应用程序使用系统java。您可以将java添加到您的exe包中。然后，应用程序使用java。如果您使用ant创建exe，则在build.xml中添加此参数;

    <javac includeantruntime="false" source="1.8" target="1.8" srcdir="build/src" destdir="build/classes" encoding="Cp1252">
        <classpath>
            <fileset dir="build/libs">
                <include name="*"/>
            </fileset>
        </classpath>
    </javac>

Answer 3

问题是这些其他计算机没有安装JavaJDK，但它们只有JavaJRE。所以我从CMD java -jar执行了jar文件，并在执行时创建了数据库表，它应该是。

由于其他计算机中的主类例外而导致失败
