阅读更多关于在 IDEA 开发环境里使用 jline 无法正常工作的问题处理

现象：在 IDEA 中开发应用，使用 jline 捕获控制台输入时，无法正常运行，主要体现在如下代码在输入回车后无法执行： ConsoleReader reader = new ConsoleReader(); reader.readLine("> "); 解决的办法：在使用 jline 之前，执行如下代码即可： jline.TerminalFactory.registerFlavor(TerminalFactory.Flavor.WINDOWS, jline.UnsupportedTerminal.class); 也可以在程序启动的命令行里增加参数 -Djline.terminal=jline.UnsupportedTerminal 搞定。来源： oschina 链接： https://my.oschina.net/javayou/blog/4768085

maven处理多版本jar包依赖冲突

mvn dependency:tree的用法一.参考文档 https://maven.apache.org/plugins/maven-dependency-plugin/examples/resolving-conflicts-using-the-dependency-tree.html https://maven.apache.org/plugins/maven-dependency-plugin/examples/filtering-the-dependency-tree.html https://maven.apache.org/plugins/maven-dependency-plugin/tree-mojo.html 二.查看jar包的间接依赖 1.如果发现某个jar包,自己的pom中并没有定义,想看一下是被哪个jar包间接引用的,两种方法 (1)用mvn dependency:tree>temp/tree.txt,直接输出到当前项目下,然后在idea中打开,搜索要找的jar包名字即可. 这里的 "+-" 和"\-"并没有什么意义,只是为了让分级看起来更直观参考:https://stackoverflow.com/questions/34006740/what-is-the-difference-between-and-in-maven-dependency

问题 I am working on a console application written in Java. What I have to do is handle user keyboard input. When a long process in launched with our program in a terminal, the user must have the possibility to press 'q' at anytime to stop the process (which is running on a separate thread). I've tried several things : Running in another different thread something that read user input and throws an InterruptedException to the process' thread Using JLine and its ConsoleReader Using JLine and add a

How can I keep the jline prompt at the bottom of the terminal? I am using jline 1, but I am open to using jline 2 if it is stable enough. 回答1: Finally figured this out... here's what you do.

How to save and load history between invocations of Scala JLine

阅读更多关于 How to save and load history between invocations of Scala JLine

问题 I'm using Scala JLine in my CLI program. It's working fine, but it forgets my history every time I restart my program. I see a class called FileHistory , and I see the ConsoleReader class has a method called setHistory() which takes an instance of FileHistory . I would expect calling that method would cause it to create or load and save a file containing my history. But it doesn't. Unfortunately the documentation is nigh nonexistent. How can I make it so the next time I run my JLine-enabled
