Error message in subproject: Could not create an instance

Help/Discuss
1

Getting the following error:

Could not create an instance of type org.gradle.api.internal.artifacts.dependencies.DefaultExternalModuleDependency_Decorated.

Error happens when executing any gradle command in the directory.

Directory structure:

Root has two children: A and B
B has child C

In directory C, which depends on subproject in A

C/build.gradle:

…
.dependencies {
compile project: (’:A’)

C/settings.gradle:

include ‘:A’
project(’:A’).projectDir = “…/…/A”

Can you provide a stacktrace via -S on the command line?

  • Exception is:

There’s a typo, it should be

compile project(':A')

without the extra colon.

Also, on a more general note: There should only be one settings.gradle file in your root project, not in your sub-projects.
