How to add a dependency to another project properly using gradle?

Question

Hello I am new to gradle and it is a little bit confusing for me. How should I add a dependency in my gradle configuration to have access to B1.java in projectA1? Project B is gradle project and project A is just a folder with another gradle projects.

Here is my structure:

1. Workspace:
   • ProjectA
     • projectA1
       • ...
       • here I want to have access to B1.java
       • build.gradle
     • projectA2
       • ...
       • build.gradle
   • ProjectB
     • projectB1
       • B1.java
       • ...
       • build.gradle
     • projectB2
       • ...
       • build.gradle
     • build.gradle

I tried to read gradle documentation, but it is not clear for me. Any help appreciated. Thanks!

You should have a structure like this:

ProjectA
|--projectA1
|----build.gradle
|--projectA2
|----build.gradle
|--settings.gradle
|--build.gradle

ProjectB
|--projectB1
|----build.gradle
|--projectB2
|----build.gradle
|--settings.gradle
|--build.gradle

You can link an external module in your project.

1) In your project projectA/settings.gradle

include ':projectA1',':projectA2',':projectB1' 
project(':projectB1').projectDir = new File("/workspace/projectB/projectB1")

2) Add dependency in build.gradle of projectA1 module

dependencies {
    compile project(':projectB1')
}
