Example 1 with MODULE_INFO_FILE

use of com.intellij.psi.PsiJavaModule.MODULE_INFO_FILE in project intellij-community by JetBrains.

the class JavaModuleGraphUtil method findCycles.

// Looks for cycles between Java modules in the project sources.
// Library/JDK modules are excluded - in assumption there can't be any lib -> src dependencies.
// Module references are resolved "globally" (i.e., without taking project dependencies into account).
