问题 What do these settings actually do? What values should a pro have on these and what impact do they have? Refactoring undo for instance, "X file has already changed so you can not undo" would be GREAT if we could throw in the garbage using any setting combination. 回答1: Based on this question the documentUndoLimit is the max level of undo for each document (actually current document) and the globalUndoLimit is the undo max level of undo for the IDE on the current project. For example, when you

问题 When I try to read some value from a user, I get strange behavior. For example, if I have one simple program: fun main() { print("insert value: ") val tmp = readLine() println("value = $tmp") } I would expect the next behavior of the program: insert value: 1 value = 1 But I get the next behavior: insert value: 1 1 value = 1 So I would expect to insert the value 1 , hit Enter , and the program would output value = 1 . But instead of this, I have to input the value 1 , hit Enter , input the

问题 Context I have a project with following traits IntelliJ Ultimate 2020.1 Java 13 (with module-info.java) Kotlin 1.3.72 JUnit (+ truth) maven (I believe this to be unimportant) The code base is mixed, some classes are written using plain Java, others with Kotlin, the same is true for tests. Everything works as expected, that is all code is compiled in proper order and fully interoperable between Kotlin and Java all test can be executed using either mvn test or IntelliJ "Run Test" the resulting
