问题 I suddenly started facing a strange issue while working on my Grails application using IntelliJ. I have different domain classes and some other classes under src/groovy . When I open a class file to make some changes, I get an error that this class already exists in package which I don't have. I tried to rename the class using refactor but after that I still get the same error. Can anybody suggest what's wrong here or if I did something wrong? 回答1: Try to "Clear" you project and build again.

问题 I have a dev *nix box. For most cases I can just ssh into the box and use emacs to develop. However, as I've started doing more Java work with very large codebases, I've realized IntelliJ IDEA is pretty invaluable. Problem: I would like to use IntelliJ IDEA on OS X, but work with a project located on some other machine. Is there a way to configure IntelliJ IDEA to do this? (over ssh/mosh/or whatever) Thanks. 回答1: I ended up just using IntelliJ locally and pointing it to a mounted server drive

问题 With SpringBoot, you have the @SpringBootApplication annotation, but what is the equivalent with the neat Java Spark framework? IntelliJ creates a Maven project and I added the spark dependency, but running the install goal, I get a 5 KB jar with no manifest. Not an executable jar. The pom.xml created thus far is as follows: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http:/

问题 I am trying to run Cucumber feature files in IntelliJ.

问题 I have following simple Scala class , which i will later modify to fit some machine learning models. I need to create a jar file out of this as i am going to run these models in amazon-emr . I am a beginner in this process. So i first tested whether i can successfully import the following csv file and write to another file by creating a jar file using the Scala class mention below. The csv file looks like this and its include a Date column as one of the variables. +-------------------+-------

问题 I am trying to add support for kotlin for one of the IDEA plugins. So far, I found this page and understood that I need to work with kotlin PSI files, such as KtClass and others. When I was setting up my project I added idea source files to sdk(by cloning this repo), to make it easier to debug + see documentation. However it seems that these idea source files doesn't include kotlin source files, such as mentioned KtClass and others, which I use in my project. Currently I see only decompiled

问题 In IDEA 15, is it a possible to display Java packages in a flat list instead of a tree?

问题 For some unknown reason, in every class where I have methods that return String type or accept String as a parameter, intellij is automatically importing: import com.sun.org.apache.xpath.internal.operations.String; Instead of java.lang.String Is this a known Bug or is there a way to disable this? 回答1: You can exclude classes from import and completion under File | Settings | Editor | General | Auto Import . Check if java.lang.String is not added there by accident. And you can add com.sun.org
