How can I pinpoint an "import cycle not allowed" problem?

How can I analyze which source file is causing the "import cycle not allowed" problem?
The error message isn't clear enough to allow me to solve the problem:

package command-line-arguments
	imports app.exap/i8/internal
	imports app.exap/i8/internal/data/retrieves
	imports app.exap/i8/internal/integration/datastore
	imports app.exap/i8/internal/objects/modules
	imports app.exap/i8/internal/data
	imports app.exap/i8/internal/integration/datastore: import cycle not allowed
package command-line-arguments
	imports app.exap/i8/internal
	imports app.exap/i8/internal/data/retrieves
	imports app.exap/i8/internal/integration/datastore
	imports app.exap/i8/internal/objects/modules
	imports app.exap/i8/internal/data
	imports app.exap/i8/internal/objects/modules: import cycle not allowed

The problem cannot be ascribed to a single source file, simply because an import cycle typically involves multiple source files from different packages.

You can glean valuable information from the error message, though: your project seems to suffer from two distinct import cycles (a 2-cycle and a 3-cycle) involving three packages:

To break those cycles, you first need to decide which edges of the cycles should be eliminated. It's difficult for me to give you definite guidance about this, though, as the best edge to eliminate is highly dependent on the context of your project.

However, a good rule of thumb for avoiding import cycles in Go is that high-level packages shouldn't depend on lower-level packages. Accordingly, you most likely do not want app.exap/i8/internal/data to depend on

• either app.exap/i8/internal/integration/datastore
• or app.exap/i8/internal/objects/modules.

Once you've decided which two edges to eliminate, simply identify which source file(s) of the importing packages contain the offending import declarations and find a way to refactor your code so as to remove them.
