What does Gradle 'build' task include exactly
提问by LazerBanana
I have searched on Gradle docs and on the stackoverflow and some other places but I can't find information about what is bundled in this task in depth, or I missed it, if so please point me to the direction.
我已经在 Gradle 文档和 stackoverflow 以及其他一些地方进行了搜索，但是我找不到有关此任务中捆绑的内容的深入信息，或者我错过了它，如果是这样，请指出方向。
- It comes from
java-baseplugin, right? - Running
gradle -q tasksdoesn't say much about it.
- 它来自
java-base插件，对吧？ - 跑步
gradle -q tasks并没有说太多。
build - Assembles and tests this project.
build - 组装和测试这个项目。
Running
gradle help --task buildshows detailed info, ok - but it show where the task is used, in which groups is included, type of a task, and paths.I have tried to track manually what does comes with it, and noticed, compile, test etc tasks.
运行
gradle help --task build显示详细信息，好的 - 但它显示任务的使用位置，包含的组，任务类型和路径。我尝试手动跟踪它附带的内容，并注意到、编译、测试等任务。
I would like to know what exactly comes from Gradle build task, what are the task dependencies.
我想知道 Gradle 构建任务究竟来自什么，任务依赖项是什么。

You can use the Gradle Task Tree Pluginto see the task dependencies
可以使用Gradle Task Tree Plugin查看任务依赖
eg:
例如：
plugins {
id "com.dorongold.task-tree" version "1.3.1"
}
Then run
然后运行
gradle build taskTree
Output
输出

Starting with version 4.0you have to run gradle build --console=plainto see the complete list of task dependencies.
从4.0 版开始，您必须运行gradle build --console=plain才能查看任务依赖项的完整列表。
If you use java-baseplugin then the dependencies are:
如果您使用java-base插件，则依赖项是：
$ gradle build --console=plain
:assemble
:check
:build
If you use java(which automatically appliesjava-base) then the dependencies are:
如果您使用java（自动应用java-base），那么依赖项是：
$ gradle build --console=plain
:compileJava
:processResources
:classes
:jar
:assemble
:compileTestJava
:processTestResources
:testClasses
:test
:check
:build
In order to see the exact chain of dependencies shown in the pictures above I used a little Perl helper that can be run inside of a Gradle project. It produces a dotstring describing dependency graph:
为了查看上图中显示的确切依赖链，我使用了一个可以在 Gradle 项目中运行的小 Perl 助手。它产生一个描述依赖图的点串：
#/bin/perl
use strict;
my @deps;
my %tasks;
getDeps($ARGV[0]);
printDot();
sub getDeps {
my $task = shift;
$tasks{$task} = "";
chomp(my @subtasks = `gradle $task`);
@subtasks = grep { $_ =~ "^:" } @subtasks;
pop @subtasks;
foreach(@subtasks) {
my ($s) = $_ =~ "^:(.*) ";
push @deps, "$task -> $s;";
if(!defined $tasks{$s}) {getDeps($s)}
}
}
sub printDot {
my $dot = "digraph main {\n";
if(@deps>1) {
foreach(@deps) {$dot .= "$_\n"}
} else {
$dot .= "$ARGV[0];\n";
}
print $dot . "}";
}
Then run the following to turn the output into a PNG image:
然后运行以下命令将输出转换为 PNG 图像：
$ t=build; perl dependencies.pl $t | tred | dot -T png > $t.png
or ASCII text:
或 ASCII 文本：
$ t=build; perl dependencies.pl $t | tred | graph-easy > $t.txt
