身為建構作者，您定義工作和工作之間的相依性。Gradle 保證這些工作會按照其相依性順序執行。
您的建構指令碼和外掛會組態此相依性圖形。
例如，如果您的專案工作包含 build、assemble、createDocs，您的建構指令碼可以確保它們按照 build → assemble → createDoc 順序執行。
建構階段
Gradle 建構有三個不同的階段。
Gradle 會按照順序執行這些階段
- 階段 1. 初始化
- 階段 2. 組態
-
-
評估參與建置的每個專案的建置指令碼，
build.gradle(.kts)。 -
為要求的任務建立任務圖表。
-
- 階段 3. 執行
-
-
排程並執行選取的任務。
-
任務之間的相依性會決定執行順序。
-
任務執行可以並行進行。
-
範例
下列範例顯示設定和建置檔案的哪些部分對應到各種建置階段
settings.gradle.kts
rootProject.name = "basic"
println("This is executed during the initialization phase.")build.gradle.kts
println("This is executed during the configuration phase.")
tasks.register("configured") {
println("This is also executed during the configuration phase, because :configured is used in the build.")
}
tasks.register("test") {
doLast {
println("This is executed during the execution phase.")
}
}
tasks.register("testBoth") {
doFirst {
println("This is executed first during the execution phase.")
}
doLast {
println("This is executed last during the execution phase.")
}
println("This is executed during the configuration phase as well, because :testBoth is used in the build.")
}settings.gradle
rootProject.name = 'basic'
println 'This is executed during the initialization phase.'build.gradle
println 'This is executed during the configuration phase.'
tasks.register('configured') {
println 'This is also executed during the configuration phase, because :configured is used in the build.'
}
tasks.register('test') {
doLast {
println 'This is executed during the execution phase.'
}
}
tasks.register('testBoth') {
doFirst {
println 'This is executed first during the execution phase.'
}
doLast {
println 'This is executed last during the execution phase.'
}
println 'This is executed during the configuration phase as well, because :testBoth is used in the build.'
}下列指令會執行上面指定的 test 和 testBoth 任務。由於 Gradle 只會設定要求的任務及其相依性，因此 configured 任務永遠不會設定
> gradle test testBoth
This is executed during the initialization phase.
> Configure project :
This is executed during the configuration phase.
This is executed during the configuration phase as well, because :testBoth is used in the build.
> Task :test
This is executed during the execution phase.
> Task :testBoth
This is executed first during the execution phase.
This is executed last during the execution phase.

This is executed during the initialization phase.
> Configure project :

This is executed during the configuration phase as well, because :testBoth is used in the build.
> Task :test
This is executed during the execution phase.
> Task :testBoth
This is executed first during the execution phase.
This is executed last during the execution phase.

2 actionable tasks: 2 executed階段 1. 初始化
在初始化階段，Gradle 會偵測參與建置的專案 (根專案和子專案) 和包含的建置。
Gradle 會先評估設定檔，settings.gradle(.kts)，並實例化一個 Settings 物件。然後，Gradle 會為每個專案實例化 Project 實例。
階段 2. 設定
在設定階段，Gradle 會將任務和其他屬性新增到初始化階段找到的專案。
