我有以下build.gradle
内容:
group 'com.example'
version '1.0-SNAPSHOT'
buildscript {
repositories {
mavenLocal()
mavenCentral()
jcenter()
maven { url "https://plugins.gradle.org/m2/" }
}
dependencies {
classpath "com.github.jengelman.gradle.plugins:shadow:2.0.1"
}
}
apply plugin: 'scala'
apply plugin: "com.github.johnrengelman.shadow"
sourceCompatibility = java_version
repositories {
mavenCentral()
}
dependencies {
// my dependencies:
compile group: 'org.apache.spark', name: "spark-sql_$scala_major", version: spark_version
testCompile group: 'junit', name: 'junit', version: '4.12'
}
问题是运行gradle build
并不会创建一个胖罐。
通过运行gradle tasks --all
查看任务依赖关系会显示shadowJar
任务存在,但build
任务不依赖于它:
:tasks
------------------------------------------------------------
All tasks runnable from root project
------------------------------------------------------------
Build tasks
-----------
assemble - Assembles the outputs of this project.
build - Assembles and tests this project.
buildDependents - Assembles and tests this project and all projects that depend on it.
buildNeeded - Assembles and tests this project and all projects it depends on.
classes - Assembles main classes.
clean - Deletes the build directory.
jar - Assembles a jar archive containing the main classes.
testClasses - Assembles test classes.
Build Setup tasks
-----------------
init - Initializes a new Gradle build.
wrapper - Generates Gradle wrapper files.
Documentation tasks
-------------------
javadoc - Generates Javadoc API documentation for the main source code.
scaladoc - Generates Scaladoc for the main source code.
Help tasks
----------
buildEnvironment - Displays all buildscript dependencies declared in root project 'scalaGradleHW'.
components - Displays the components produced by root project 'scalaGradleHW'. [incubating]
dependencies - Displays all dependencies declared in root project 'scalaGradleHW'.
dependencyInsight - Displays the insight into a specific dependency in root project 'scalaGradleHW'.
dependentComponents - Displays the dependent components of components in root project 'scalaGradleHW'. [incubating]
help - Displays a help message.
model - Displays the configuration model of root project 'scalaGradleHW'. [incubating]
projects - Displays the sub-projects of root project 'scalaGradleHW'.
properties - Displays the properties of root project 'scalaGradleHW'.
tasks - Displays the tasks runnable from root project 'scalaGradleHW'.
Shadow tasks
------------
knows - Do you know who knows?
shadowJar - Create a combined JAR of project and runtime dependencies
Verification tasks
------------------
check - Runs all checks.
test - Runs the unit tests.
Other tasks
-----------
compileJava - Compiles main Java source.
compileScala - Compiles the main Scala source.
compileTestJava - Compiles test Java source.
compileTestScala - Compiles the test Scala source.
processResources - Processes main resources.
processTestResources - Processes test resources.

The 'build' task in Gradle is commonly mistaken用于构建项目中所有任务的任务。 '构建' task实际上是由java-base插件提供的,包括以下任务:
compileJava, processResources, classes, jar, assemble, compileTestJava, processTestResources, testClasses, test, and check
而不是运行' gradle build'我建议使用defaultsTasks
`defaultTasks 'build', 'shadowJar'`
将该行放在build.gradle中将允许在没有参数的情况下调用Gradle,以便同时运行build和shadowJar。
> gradle
我不熟悉shadowJar插件,但是如果它暴露了一个名为shadowJar的任务,那么在build.gradle中使用dependsOn行可以简化defaultTasks行。
project.tasks.shadowJar.dependsOn build
将defaultTasks行简化为
defaultTasks shadowJar
