任何人都可以更明确地说明问题所在的位置,以及如何解决问题?
我正在跑步:
我已经仔细地按照说明仔细阅读了关于code.makery.ch的Marco教程(code.makery.ch/library/javafx-8-tutorial/part7 /)
我之前已部署此程序的早期原生包,但有些麻烦,但最终成功添加后
-vm
C:\Program Files\Java\jdk1.8.0_91\bin\javaw.exe
到eclipse.ini
最终让ant build成功运行后,
do-deploy:

//Icon from https://icons8.com
@Override
public void start(Stage primaryStage) throws Exception{
loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/Arrivals_Layout1.fxml"));
Parent root = loader.load();
primaryStage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("resources/images/Pallet-96.png")));

如果有帮助,我的Package Explorer看起来像this

生成.exe并将程序安装在/ AppData中。
该程序将在Eclipse中编译并运行良好,但是当我运行已安装的版本时,我得到:
首先调用方法时出错。
然后单击确定
无法启动JVM
我似乎尝试了一切:
我已经阅读过多个类似的问题,并且已经浏览过互联网,但还没有发现这个问题。我读过的许多例子含糊不清或没有答案:
因为他在部署方面不那么精通,所以Marco自己说要问Stack Exchange的强大世界: http://code.makery.ch/library/javafx-8-tutorial/part7/#comment-2233862311
再次说明我的问题所处的具体问题,以及如何解决问题?
答案 0 :(得分:3)
我明白了!
经过双重,三重检查依赖关系并看到它编译后再构建好,我怀疑jar文件位于build/deploy/{yourProjectName}.jar
编辑:如果您只在安装错误后才收到错误,那么在安装目录中运行jar是有意义的。 (AppData/Local/{ApplicationTitle}/app/{yourProjectName}.jar
)
我在命令行上运行它以查看它是否抛出异常:
轻松导航到我记下的目录,我在Explorer中保存了项目,然后将其复制到命令行。
打开命令提示符
赢 + r
cmd
+ 输入
导航到目录
cd {ProjectPath}\build\deploy
运行jar文件
java -jar "{YourJar}.jar"
因为我是通过命令提示符执行jar的,所以java有一个地方可以向我显示异常!
C:\Users\administrator.SUNDANCE\IdeaProjects\PODTester_Layout8\build\deploy>java
-jar "PODTester_Layout8.jar"
java.io.FileNotFoundException: src\resources\Carrier List.txt (The system cannot
find the path specified)
at java.io.FileInputStream.open0(Native Method)
at java.io.FileInputStream.open(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
在审核我的代码后,由于明确引用src
,我认为它没有找到该文件。我解决了这个问题,看哪!重建后,已安装的应用程序正常运行!
如果您的原生套餐会抛出
调用方法时出错。
和
无法启动JVM
通过命令提示符运行您的jar文件,看它是否会引发异常。
现在,如果您想了解我的具体问题以及我修复过程的详细信息,请点击此处:
我认为它可能与依赖关系有关(特别是对我来说包括sqljdbc驱动程序),但事实证明它不是一个依赖问题。问题是 .jar只在安装时抛出了一个例外。是什么让错误如此难以理解的是哦,如此通用&#34;无法调用方法。&#34;这给了我很少的新信息。
为了缓解未来类似问题,我添加了showExceptionDialog()
方法(受Marco Jacob's work启发):
/**
* Shows a dialog box when an exception occurs instead of just doing nothing.
*
* Once installed this will help to diagnose problems instead of letting
* them go unnoticed.
*
* @param e the exception to print; it's stacktrace will be shown as well
*/
public static void showExceptionDialog(Exception e) {
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("Exception Dialog");
alert.setHeaderText("An error occurred:");
String content = "Error: ";
if (null != e) {
content += e.toString() + "\n\n";
}
alert.setContentText(content);
Exception ex = new Exception(e);
//Create expandable Exception.
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
ex.printStackTrace(pw);
String exceptionText = sw.toString();
//Set up TextArea
TextArea textArea = new TextArea(exceptionText);
textArea.setEditable(false);
textArea.setWrapText(true);
textArea.setPrefHeight(600);
textArea.setPrefWidth(800);
//Set expandable Exception into the dialog pane.
alert.getDialogPane().setExpandableContent(textArea);
alert.showAndWait();
}
在我的程序中,我有一个名为Carrier List.txt
的文件被读取和写入,并存储在resources
文件夹中。
在IntelliJ和Eclipse中,它编译得很好,因为它可以很好地找到src/resources/Carrier List.txt
。当按照Marco Jacob's Deployment Tutorial手动复制资源文件夹时,情况会很好,但我明确引用了
src / resources / Carrier List.txt
在我的代码中,而不仅仅是
resources / Carrier List.txt
