问题 What does the inject method in Groovy actually do? I googled it, and have not found the exact answer. Can anyone specify its use with a simple example? 回答1: It applies an operation to a collection and keeps track of an intermediate value. Take this example: [1, 2, 3, 4].inject(0, { sum, value -> sum + value }) . This says use 0 as the initial value and apply the addition operation to the intermediate result and each element in sequence. Each application of the operation generates a new

问题 IDEA is giving my groovy class the warning `class "MyClassTest" already exists in "my.class.package". It also doesn't seem to be doing a very good job of keeping the class updated when I run the test. I'll add an assertion guaranteed to fail, or succeed and it won't recognize it until later (later so far seems arbitrary). Given that I have maven tests passing and running correctly I suspect this is simply an IDEA configuration problem here's my pom.xml <?xml version="1.0" encoding="UTF-8"?>

问题 We are using Jenkins to automate several of our build and test processes. For some of our process, the engineer starting the build needs to specify a parameter. But the range of possible and optimal values for that parameter change throughout the course of the day. What I would like to do is let the engineer specify a value - if they know an optimal value - or leave it blank and have a value be calculated by an early build step. If the value is calculated, I would like the calculating build
