是否有获取jSoup jar版本的方法? [英] Is there a method to get the jSoup jar version?

问题描述

我不是Java程序员，而是在ColdFusion应用程序中使用jSoup，而且我的Java知识是有限的.

I am not a java programmer and I am using jSoup in a ColdFusion application, and my java knowledge is limited.

我查看了文档，但是找不到一种方法来告诉我加载了哪个版本的jSoup.也许有一个标准的Java方法吗?

I looked in the docs but could not find a method to tell me which version of jSoup is loaded. Maybe there is a standard java method for that?

这是必要的，因为我正在共享主机上使用它，并且我想确保已加载正确的兼容版本.

It is necessary because I am using it on a shared hosting and I want to ensure I have the correct compatible version loaded.

谢谢， 默里

推荐答案

通常，您可以向Java运行时环境提供要在类路径中某处使用的库版本，或者使用构建工具来管理以下项的依赖关系:你.

Usually you either supply the java runtime environment with a version of the library you want to use somewhere on the classpath, or you use a build tool to manage dependencies for you.

通常情况下，后者是首选.

Typically the latter is preferred.

例如我几乎对每个项目都使用gradle.要将gradle添加到您的项目中，请下载/安装gradle，打开一个终端，使用cd进入该项目的根目录，执行gradle init，然后在项目中最终得到一些其他文件.

e.g. I use gradle for just about every project. To add gradle to your project, download/install gradle, open a terminal, cd to the project's root dir, execute gradle init and then you end up with a few additional files in your project.

项目根目录中的文件之一是build.gradle，其中包含许多内容-一个是项目dependencies.这是我用于JSoup项目的一个示例:

One of the files in the project's root dir is build.gradle this contains many things - one is the project dependencies. Here's an example of one I use for JSoup projects:

plugins {
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

test { useJUnitPlatform() }

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.jsoup:jsoup:1.10.2'
    implementation 'com.jayway.jsonpath:json-path:2.4.0'

    testImplementation 'org.junit.jupiter:junit-jupiter:5.7.0'
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
}

在这里您可以看到库依赖项的确切版本，如果要检查由于另一个库导入了您期望的其他/较新版本而导致的版本冲突，则可以使用gradle dependencies进行检查.

Here you can see the exact version of the library dependency and you can check it with gradle dependencies if you wanted to check for a version clash due to another library importing a different/newer version you weren't expecting.

另一种方法就是简单地下载库，并将其放置在类路径中的某个位置，以便您的应用程序可以访问它.

Another method is simply to download the library and place is somewhere on the classpath so your application can access it.
