The question is published on by Tutorial Guruji team.
Is it possible to make gradle rosolve android project’s dependencies dynamically like ant does?
What I want to acheeve is to be able to add/remove library projects (modifieng only project.properties file for corresponding project) without a need to rewrite buil.gradle script.
Ant resolves it by reading project.properties recursively getting a list of all library projects involved into specific build with the following prdefined task:
<getlibpath projectPath="${basedir}" libraryFolderPathOut="project.library.folder.path" />
What I’ve found currently in gradle is to define a list of projects manually in settings.gradle:
include 'GradleTest_lib1'
include 'GradleTest_lib2'
project(':GradleTest_lib1').projectDir = new File('../GradleTest_lib1')
project(':GradleTest_lib2').projectDir = new File('../GradleTest_lib2')
And add dependecies into build.gradle file:
dependencies {
compile fileTree('libs')
compile project('GradleTest_lib1')
compile project('GradleTest_lib2')
}
I beleive I’m missing something and there should be a simple way to find and compile all the lib-projects ‘on the fly’
Answer
Currently I solved this task with the following script
settings.gradle:
def props = readAllLibProjects()
println props
loadLibProjectsFromProps(props)
def Properties readAllLibProjects(){
def props = new Properties()
return readAllLibProjects("", props, 1)
}
def Properties readAllLibProjects(String basePath, props, int level){
Properties localProps = new Properties();
new File(basePath + "project.properties").withInputStream {
stream -> localProps.load(stream)
}
localProps.each{
String key = it.key
String value = it.value
if(key.contains("android.library.reference")){
key = key + "_" +level;
props.put(key, value);
readAllLibProjects(it.value + "/", props, level + 1)
}
}
return props
}
def loadLibProjectsFromProps(Properties props){
props.each{
if(it.key.contains("android.library.reference")){
String projectPath = it.value;
String projectName = projectPath.split("/").last();
include projectName
project(":"+projectName).projectDir = new File(projectPath);
println "project's path = " + projectPath;
println "project's name = " + projectName;
}
}
}
and build.gradle:
dependencies {
compile fileTree('libs')
subprojects.findAll{
compile project(it.name)
}
}
