This question has already been answered:

There is the following structure

MainProject settings.gradle build.gradle Proj1 build.gradle Proj2 build.gradle

In the MainProject/settings.gradle I prescribe projects

 include 'Proj1', 'Proj2'

Proj2 requires classes from Proj1 , so in Proj2/build.gradle I am writing

 dependencies { compile project(':Proj1') //other dependencies }

When I do gradle :Proj2:compileJava I have written that the package (from Proj1 ) was not found, so the compilation ended with an error.

What am I doing wrong?

    Found a solution.

    You must write the MainProject/build.gradle in MainProject/build.gradle

     project(':Proj2') { dependencies { compile project(':Proj1'); } }

    and the Proj2 Proj2/build.gradle must be deleted.

    Accordingly, the question arose - why it does not work as I wrote in the question, but this is another question .
