How to read string from file using Groovy in QuickBuild

Question

I am new to QuickBuild.

I have a lot of different versions stored in text files.
To start the build process, I need to retrieve the versions from the text files and pass them to a shell script.

My question is:
I know that it supports Groovy, MVEL and OGNL languages but I'm not familiar with any of them.

Thanks in advance.

Answer 1

I found the solution :)

${groovy: str = new java.io.File("[PATH_TO]/file.txt").text}

or

${groovy: str = new java.io.File("[PATH_TO]/file.txt").text
str.split("[\\r\\n]")[0] } 

to read the first line only.

Thanks to me :)

稍微短一点的版本，只读取第一行（不对EOL字符做任何假设）：

${groovy: str = new File("[PATH_TO]/file.txt").readLines()[0] }
