使用同一罐子的多个模块 [英] Multiple modules using the same jar

问题描述

我有一个包含多个模块的项目.一些模块依赖于同一个jar.现在，每个模块都有自己的"libs"文件夹，其中包含2个相同库的jar.更新jar文件可能会出现问题，因为我现在必须更改所有模块中的所有jar.另外，我遇​​到一个编译问题，说有重复的类.一种解决方法是从除一个模块之外的所有模块中删除jar文件.这是唯一的方法还是有更好的方法?

I have a project with several modules. Some modules depends on the same jar. Right now each of the modules have their own "libs" folder containing 2 jars of the same library. Updating a jar file can be problematic since I will now have to change all the jars from all of the modules. Also, I encounter a compilation problem saying that there are duplicate classes. One workaround is to remove the jar files from all of the modules except for one. Is this the only way to do it or is there a better way?

推荐答案

我已经能够解决此问题.此阅读有关Gradle的信息对我有很大帮助.这是我所做的:

I have been able to fix this issue. This reading about Gradle helped me a lot. Here is what I have done:

我没有将JAR file放入moduleA/libs folder中，而是通过单击project then right click -> new -> module将JAR file导入了Android Studio中.然后，我单击Import .JAR/.AAR package.这样创建了module containing the JAR file + a gradle script.

Instead of putting the JAR file in moduleA/libs folder, I have imported the JAR file in Android Studio by clicking on the project then right click -> new -> module. I then clicked on Import .JAR/.AAR package. This created a module containing the JAR file + a gradle script.

然后，在moduleA’s gradle script中，我已将其添加到dependencies中:compile project(path: ':name_of_the_jar_file')

Then, in moduleA’s gradle script, I have added this in the dependencies: compile project(path: ':name_of_the_jar_file')

我重新构建了所有文件，并且一切正常. JAR file现在出现在APK中，并且在运行时不再崩溃.

I rebuilt all and it works. The JAR file is now present in the APK and there is no more crash at runtime.
