How to replace in log4j2.xml with Gradle? - gradle

Question

I want to replace a value in our log4j2.xml with Gradle during build. I found a way to do that:
task reaplaceInLogFile {
String apiSuffix = System.properties['apiSuffix'] ?: ''
println "In my task"
String contents = file('src/main/resources/log4j2.xml').getText( 'UTF-8' )
println "File found"
contents = contents.replaceAll( "svc0022_operations", "svc0022_operations${apiSuffix}")
new File( 'src/main/resources/log4j2.xml' ).write( contents, 'UTF-8' )
}
However, this changes also the source file permanently and I do not want to do that. I want to change the log4j2.xml that will be included in the build zip only. I know I can use something like this:
tasks.withType(com.mulesoft.build.MuleZip) { task ->
String apiSuffix = System.properties['apiSuffix'] ?: ''
task.eachFile {
println name
if (name == 'mule-app.properties') {
println "Expanding properties for API Version suffix: ${apiSuffix}"
filter { String line ->
line.startsWith("${serviceId}.api.suffix") ? "${serviceId}.api.suffix=${apiSuffix}" : line
}
}
But I do not know what is the type of the log4j2 file. If there is another way to do that I will be thankful!
We are using Mule gradle plugin.

The Type is not the type of the log4j2 file, but the type of the task that creates the ZIP or wherever your log4j2 file is packaged into. If the log4j2 file is included in the ZIP that is generated by a MuleZip task, then you can simply add another if-branch for the log4j2 file.
But actually it is probably better to just edit the concrete task that packages up the log4j2 file into some archive instead of all tasks of the same type.
Besides that you should be able to use filesMatching instead of eachFile with an if I think.
