使用IDEA的时候有时要用到eclipse的user library，由于两个IDE导入library的方式不同导致我们找不到导入user library的方法。

查IDEA的官方文档，找到方法如下：

首先要导入user library ：

那么我们在IDEA下要导入的就是Global library。

导入后加到module中，libray有个选项叫做Scope ，有如下值Compile Test Runtime Provided

Scope

Use this drop-down to affect the classpath for the various build phases.

Compile: This is the default option. If it is selected, the dependency is resolved and is available in classpath during the compilation and run phases.
Test: Select this option, if this dependency is only required for tests, and should not be available in normal application use. If this scope is selected, the dependency is resolved and is available in classpath during the test
compilation and run phases.
Runtime: This scope indicates that the dependency is only required when running the application, and should not be available in classpath during the compilation.
Provided: If this option is selected, the dependency is resolved and is available in classpath during the compilation, but is not included in classpath at runtime. This dependency scope is useful, when you have some container
that provides the dependency at runtime.

由于我们要加入的是动态加载的库，所以要求编译的时候不加载，只有在运行用到的时候调用。

所以Scope选择Provided选项。

默认是Compile，编译的时候会随module进行编译，此处要改为Provided

搞定。

现在有个需求是这样。module A要用到user library，module A 使用上述方法将user library 导入，并将order 放置在Andorid SDK的上面。

module B要Dependency A

在mudule B中把A作为依赖库导入，Scope选择Provided ，出现如下错误

java.lang.VerifyError

是因为库的导入方式不对，

mudule B中把A作为依赖库导入，Scope选择Compile 。搞定
