windows - 运行 Gradle 应用程序分发时的编码问题
问题描述
我正在使用 Eclipse 中的 Gradle 开发这个 JavaFX 应用程序。操作系统是 Windows10,但我主要使用 Cygwin ......
在一个牢房里,TableView
我有一个String
“référé”。
它是用 Groovy 编写的。当我使用 Eclipse 中的 Groovy 控制台运行应用程序时,Stage
会显示并String
显示 OK。
但是当我这样做时
$ ./gradlew installdist
...然后使用(Cygwin)在分发目录中运行该应用程序
$ ./MyApp
或(Windows 命令提示符)
D:\My Documents\software projects\operative\MyApp\1.0.0\bin>MyApp.bat
... theString
显示不正确:“é”字符显示为带有白色问号的黑色菱形。
在 Cygwin 我试过这个:
$ cmd /c chcp 65001
响应:“活动代码页:65001”。但之后运行该应用程序仍然会产生此编码错误。像这样的编码问题的麻烦在于我不知道从哪里开始......这是否往往表明 Cygwin 和 Windows 命令控制台都使用“不正确”的编码......这在某种程度上是“传染性的”从他们运行的任何应用程序?
如何找到它们各自的编码...以及如何使应用程序以 UTF-8 运行?

解决方案
有趣……没多久。我建议将其留在这里,因为似乎没有其他问题涉及此问题。
在 Eclipse 中,我将焦点放在 .groovy 文件中,然后按 Alt-Enter(文件 --> 属性)。
This showed a dialog with the first page showing called "Resource". At the bottom, under "Text file encoding" the radio button was set at "Default (inherited from container: Cp1252)".
- Changed to the "Other" radio button and chose "UTF-8".
- Apply and Close
This messed up the String
in question in the file itself (same weird bad encoding). When I re-entered "référé" correctly, and did another Gradle distribution, and ran the shell file (./MyApp), it worked OK: the encoding was correct.
PS I have to wait 2 days before I can accept my own answer. Other answers may shine some unexpected light on this.
