Groovy: Replacing a character sequence in a String and loading Properties from a file
Published on 17 July 2019
Here is a piece of working Groovy code to replace all occurrences of a character sequence in a String, load a .properties file into a properties object, and execute a command within a String. replaceTextinFile.groovy
#!/usr/bin/env groovy
println System.getProperty("user.home")
static String getSeparator_() {
System.getProperty("file.separator")
}
String separator = separator_
String path = System.getProperty("user.home")
.concat("${separator}.gradle" +
separator +
"gradle.properties")
File propertiesFile = new File(path)
assert propertiesFile.exists() && !propertiesFile.directory
Properties gradleProperties = new Properties()
propertiesFile.withInputStream { InputStream it ->
gradleProperties.load(it)
}
String user_name = gradleProperties.getProperty("user_name")
String text
String resultText
text = new File("${System.getProperty("user.home")}" +
separator +
"src" +
separator +
"cheroliv.github.io" +
separator +
"src" +
separator +
"main" +
separator +
"resources" +
separator +
"eco_space.txt").text
String to = separator +
"media" +
separator +
"${user_name}" +
separator +
"320" +
separator +
"videoCours" +
separator
String from = "${System.getProperty("user.home")}" +
separator +
"p2p" +
separator
resultText = text.replace(to, from)
println resultText
//execute command line in a string
println "rsync -avr ${resultText} ${to}".execute().text
