我正在为 SonarQube 开发一个插件，它必须做的一部分是将文件从自身复制到 SonarQube 服务器的目录.我正在使用 Apache Commons IO，并且发现 FileUtils.copyDirectory 工作得非常好(在使用 main 方法对其进行测试之后).
麻烦来自试图从插件本身的 jar 中获取我想要复制的文件目录.我试过这个:
I am developing a plugin for SonarQube, and part of what it must do is copy files from itself to the SonarQube Server's directory. I am using Apache Commons IO, and have found that FileUtils.copyDirectory works wonderfully (after testing it with a main method).
The trouble comes from trying to get the directory of files that I want to copy from the jar of the plugin itself. I have tried this:
public File getSrcDir() {
URL inputUrl = getClass().getResource("/images");
File srcDir = FileUtils.toFile(inputUrl);
System.out.println(srcDir);
return srcDir;
}
当我在 IDE (Eclipse) 的 main 方法中运行它时，它会打印出 C:...[Project Directory] argetclassesimages但是，当我将插件作为 Sonar 的插件"文件夹中的 jar 文件夹安装到 SonarQube 中时，此方法会打印出 null.
我调查发现 FileUtils.toFile(URL url) 如果 url 参数的协议不是文件"，则将返回 null.所以我在我的方法中添加了这一行:System.out.println(inputUrl.getProtocol());
果然，在我的IDE中，协议是文件"，但是当我安装插件时，协议是jar"！
我花了最后一天倾注于 Stack Overflow 和 Google 试图找到解决此问题的方法，但无济于事.
我愿意尝试/重构任何东西.
我要做的就是让我的插件将其 jar 中的目录复制到 SonarQube 的服务器.
我该怎么做?
如果相关，这是我项目中的目录(我想复制图像"文件夹及其中的所有内容):
When I run it in a main method in my IDE (Eclipse), it prints out C:...[Project Directory] argetclassesimages
But when I install the plugin into SonarQube as a jar folder in Sonar's "plugins" folder, this method prints out null.
I investigated and found that FileUtils.toFile(URL url) will return null if the url argument has a protocol other than "File". So I added this line to my method: System.out.println(inputUrl.getProtocol());
Sure enough, in my IDE the protocol is "file", but when my plugin is installed the protocol is "jar"!
I have spent the last day pouring over Stack Overflow and Google trying to find a way to deal with this, but to no avail.
I am willing to try/refactor anything.
All I want to do is make it so that my plugin copies a directory from within its jar to SonarQube's Server.
How can I do this?
In case it's relevant, here is the directory within my project (I want to copy the "images" folder and everything in it):
[Project Directory]
|
+--/src/main/resources
|
+--images
|
+--profiles
|
+--awards
| |
| +--Award1.png
| |
| +--Award2.png
|
+--projects
|
+--default.png
这里是 SonarQube 服务器中要复制到的目录:[SONARQUBE_HOME]/war/sonar-server/images
And here is the directory to copy to in the SonarQube server:
[SONARQUBE_HOME]/war/sonar-server/images
当classpath中的资源(这里是图片或目录)来自jar时，不再是物理文件
When resource (in this case images or directory) in classpath coming from jar, it is no longer a physical file
您需要修改代码，使其从 Stream 而不是 File
You need to modify the code so that it reads those resources from Stream instead of File
