在 Groovy 中如何替换文件中的字符串？

Question

I'm following the answer given in Replace the string in file using groovy , but am getting an error. I just want to replace, for example

From
version=1.1.0

To
version=1.1.1

in some file. I do

String sv1 = '1.1.0'
String sv2 = '1.1.1'
def file = new File(`/some_path/someFile')
def fileText = file.replaceAll("version=$sv1", "version=$sv2")
file.write(fileText)

I get

Caught: groovy.lang.MissingMethodException: No signature of method: java.io.File.replaceAll() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl, org.codehaus.groovy.runtime.GStringImpl) values: [version=1.1.0, version=1.1.1]

Are the dots (.) in the string messing it up? What's the proper syntax if so? Thanks.

Answer 1

您需要在文件的内容上调用replaceAll() ，而不是在File实例本身上。

def fileText = file.text.replaceAll("version=$sv1", "version=$sv2")

Answer 2

这将在一行中完成您的整个任务

new File(`/some_path/someFile').text=new File(`/some_path/someFile').getText().replaceAll("version=1.1.0", "version=1.1.1")
