Hi Guillaume,
If you really want to replace tokens straight in your source files, which 2
other posters already discouraged, i've gona ahead and made a small sample that
replaces tokens in your main sourceset:
apply plugin: 'java'
def version = '1.1'
def filteredSourceDir = file("${buildDir}/filtered")
sourceSets {
// This source set will contain all sources that we filter
filtered {
java {
srcDirs = [filteredSourceDir]
}
}
}
// tell the compileJava task to compile the filtered source
compileJava.source = sourceSets.filtered.java
// copy the main sources and filter any '$version' occurences.
task processVersion (type: Copy) {
from sourceSets.main.java
into filteredSourceDir
expand(version: '1.1')
}
compileJava.dependsOn processVersion
The above buildscript would transform a function like this
public String getVersion () {
return "$version";
}
Into:
public String getVersion () {
return "1.1";
}
Whether or not this is good practice is not for me to judge ;)
Hope this helps!
