我不明白问题是什么,为什么他发誓找不到 locale en
. 路径或路径有问题吗 boundle
名字?
这个 legacy
这个项目写在15年前,曾经是 Ant
,现在它被翻译成 Gradle
,出现此错误。它建立在 Ant
没有问题。
p、 我在类中分别标记了错误所指的行。

Exception in thread "main"
Execution failed for task ':Tracker.main()'.
从日志中可以看出,所有错误都是由于找不到locale en而导致的。

gradle不会在属性文件处于
src/main/java
文件夹。你有两个选择。1.选项:将下面的脚本添加到
build.gradle
. 它将在java编译之后运行,并将所有属性文件复制到build目录中。选择此选项可避免更改文件位置。chiriki的回答建议(我也同意)
processResources
任务独立运行,尽管任何java代码都没有更改。compileJava.doLast
只运行java代码需要编译阶段,稳定性有差距。因此,选择下面的脚本作为第一个选项。2.选项:将属性文件移到资源文件夹中
src/main/resources
. 选择此选项可获得最佳布局结构。非编译文件应位于resources文件夹中。dy2hfwbg2#
我不明白这些课程的作用
control_res
以及control_res_en
在那种情况下。有相应的*.properties
并通过ResourceBundle
应用程序编程接口;在我看来,这些课程已经过时了。当然,对于gradle(或者maven,如果这也是一个选项的话),必须将属性文件存储为资源(在
/src/main/resources
,通常),或者相应地调整构建过程,否则文件将无法进入最终jar…但据我了解,真正的问题是线路造成的
从中的构造函数
control_res
.res
有价值吗control_res.properties
; 这意味着(根据提供的屏幕截图),程序在文件夹中查找属性文件~/org/opensourcephysics/resources/controls
(参见此处),但从同一屏幕截图来看,文件似乎存储在~/org/opensourcephysics/resources/controls/Resource Bundle 'controls_res'
(我不得不说,这是一个很奇怪的名字,但截图是这样的……)。糟糕的是
Class.getResourceAsStream()
我会回来的null
如果请求的资源丢失…5ktev3wc3#
i中的选项2̇smail durmaz的答案应该是完美的解决方案:我还建议将所有资源文件移动到
src/main/resources
. fwiw,gradle文档的这一部分解释了源代码集如何区分java源文件和其他资源。但是,如果您不能将属性文件移动到新位置,那么有一个比我更好的解决方案̇smail的第一个选择是改变
processResources
同时从中复制属性文件的任务src/main/java
:这有以下优点:
你的
compileJava
任务只负责编译,它可以安全地决定UP-TO-DATE
当没有变化的时候。与我̇斯梅尔的回答是compileJava
即使没有任何更改,任务也可能始终运行:gradle看到任务的输出目录是脏的(因为它不知道有属性文件),因此将重新运行整个编译以确保安全。这显然是在浪费构建时间和计算资源。为此,资源与常规任务一起复制(
processResources
).
