任何人都可以更具体地对我的问题所居住的地方和如何修复?
我正在运行:
- Windows 7
- Eclipse Mars.2版本(4.5.2)
我已经仔细遵循了Marco上的指示。Marco在Code.makery.ch(code.makery.ch/library/javafx-8-tutorial/part7/part7/)
之前,我已经部署了此程序的较早本机软件包,但有些麻烦,但最终在添加
之后成功地成功了-vm

to eclipse.ini
最终成功运行蚂蚁之后,

生成.exe并在/appdata中安装程序。
该程序将在Eclipse中编译并运行良好,但是当我运行安装版本时,我会得到:
错误调用方法。
首先,然后单击OK
无法启动JVM
我似乎尝试了一切:
我已经阅读了多个类似的问题,并且已经搜寻了互联网,但是尚未衡量这个问题。我读过的许多人都有含糊或没有答案的示例:
错误调用方法,无法启动JVM
javafx本机pakage错误调用方法
因为他在部署方面不太熟练,所以马可本人说来询问堆栈交流的强大世界:http://code.makery.ch/library/javafx-8-tutorial/part7/#comment-2233862311
再次,关于我的问题所在的位置以及如何修复它的任何特定启示?
我发现了它!
我发现问题的方式:
double之后,三重检查依赖项并看到它既编译然后构建正常,又怀疑位于 build/deploy/{yourProjectName}.jar
编辑:如果您仅在安装错误后得到错误,则在安装目录中运行JAR是有意义的。(AppData/Local/{ApplicationTitle}/app/{yourProjectName}.jar
)
我在命令行上运行它,以查看它是否正在抛出例外:
要轻松导航到目录,我指出了我将项目保存在Explorer中的位置,然后将其复制到命令行。
打开命令提示
win r
cmd
enter导航到目录
cd {ProjectPath}builddeploy
运行jar文件
java -jar "{YourJar}.jar"
因为我是通过命令提示执行罐子的,所以爪哇可以向我展示例外!
C:Usersadministrator.SUNDANCEIdeaProjectsPODTester_Layout8builddeploy>java
-jar "PODTester_Layout8.jar"
java.io.FileNotFoundException: srcresourcesCarrier 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)
查看我的代码后,我认为由于src
的明确引用,它没有找到该文件。我修复了,然后看!重建后,已安装的应用程序工作!
因此,总结:
如果您的本机软件包会抛出
错误调用方法。
和
无法启动JVM
通过命令提示运行JAR文件,查看是否引发异常。
现在,如果您想要有关我的特定问题的详细信息以及我要修复的过程,那么您就可以了:
问题:
我认为这可能与依赖关系有关(尤其是与我在内的SQLJDBC驱动程序)有关,但事实证明,这不是一个依赖问题。问题是 .jar曾经安装了一个例外一旦安装。使错误如此难以理解的是OH-So-So-seneric"无法调用方法"。"这给了我很少的新信息。
为了减轻未来的类似问题,我添加了showExceptionDialog()
方法(受Marco Jacob的工作启发):
/**
* 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() + "nn";
}
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();
}
有关我问题的具体细节:
在我的程序中,我有一个名为 Carrier List.txt
的文件被读取并写入到resources
文件夹中。
在Intellij和Eclipse中,它可以很好地编译,因为它可以找到src/resources/Carrier List.txt
。当我根据Marco Jacob的部署教程手动复制资源文件夹时,情况就很好了,但是我明确引用了
src /resources/carrier list.txt
在我的代码中而不是
中资源/运营商列表
