建立multi-project，须要在rootProject的目录下新建settings.gradle.java
目录: I:\gretty\hello-gradle\multi-Project Mode LastWriteTime Length Name ---- ------------- ------ ---- d---- 2014/11/8 14:04 .gradle d---- 2014/11/8 14:00 flower d---- 2014/11/8 14:00 tree -a--- 2014/11/8 14:11 267 build.gradle -a--- 2014/11/8 14:05 23 settings.gradle
根据上面的目录咱们能够像这样设置settings.gradlegradle
include 'tree','flower'
执行gradle projectsui
PS I:\gretty\hello-gradle\multi-Project> gradle projects :projects ------------------------------------------------------------ Root project ------------------------------------------------------------ Root project 'multi-Project' +--- Project ':flower' \--- Project ':tree' To see a list of the tasks of a project, run gradle <project-path>:tasks For example, try running gradle :flower:tasks BUILD SUCCESSFUL Total time: 4.414 secs
这样咱们就新建了一个gradle 的multi-project的项目。lua
涉及到multi-project的设置，有allProjects subProjects，能够对其进行配置。code
1 allProjects，包括rootProject和全部的subProject均可以根据allProject中的配置构建项目。it
allprojects {
task printInfo << {
println "This is ${project.name}"
}
咱们执行gradle printInfo
PS I:\gretty\hello-gradle\multi-Project> gradle printInfo
:printInfo
This is multi-Project
:flower:printInfo
This is flower
:tree:printInfo
This is tree
BUILD SUCCESSFUL
Total time: 6.189 secs
能够看到rootProject和subProject都执行task printInfo。ast
2 subprojects,只有子项目执行的任务class
subprojects {
task printInfo << {
println "Can be planted"
}
}
PS I:\gretty\hello-gradle\multi-Project> gradle printInfo
:flower:printInfo
Can be planted
:tree:printInfo
Can be planted
BUILD SUCCESSFUL
3 咱们还可使用project(":tree"),来指定项目运行任务配置
allprojects {
task printInfo << {
println "This is ${project.name}"
}
}
subprojects {
printInfo << {
println "Can be planted"
}
}
project(':tree').printInfo << {
println "Has leaves"
}
project(':flower') {
printInfo.doLast {
println 'Smells nice'
}
}
执行 gradle printInfo
PS I:\gretty\hello-gradle\multi-Project> gradle printInfo
:printInfo
This is multi-Project
:flower:printInfo
This is flower
Can be planted
Smells nice
:tree:printInfo
This is tree
Can be planted
Has leaves
BUILD SUCCESSFUL
Total time: 8.444 secs
从上面的输出咱们也能够看得出任务的执行顺序。im
4 过滤配置
allprojects {
task printInfo << {
println "This is ${project.name}"
}
}
configure(allprojects.findAll { it.name.startsWith('f') }) {
printInfo << {
println 'Smells nice'
}
}
PS I:\gretty\hello-gradle\multi-Project> gradle printInfo
:printInfo
This is multi-Project
:flower:printInfo
This is flower
Smells nice
:tree:printInfo
This is tree
BUILD SUCCESSFUL
Total time: 8.195 secs
使用afterEvaluate 进行过滤
allprojects {
task printInfo << {
println "This is ${project.name}"
}
}
subprojects {
afterEvaluate { project ->
if (project.hasLeaves) {
project.printInfo << {
println 'Has leaves'
}
}
}
}
project(':flower') {
ext.hasLeaves = false
}
project(':tree') {
ext.hasLeaves = true
}
执行gradle printInfo
PS I:\gretty\hello-gradle\multi-Project> gradle printInfo
:printInfo
This is multi-Project
:flower:printInfo
This is flower
:tree:printInfo
This is tree
Has leaves
BUILD SUCCESSFUL
