Brief introduction

Gradle is a project automation build tool based on Apache Ant and Apache maven that declares build settings using a particular domain-specific language (Domain-specific language DSL) based on groovy. Support multi-language project building, including Android, C + +, Groovy, Java, Javascript, Kotlin, Scala.

Official website https://gradle.org/. Https://gradle.org/releases/.

Installation

As with Maven, unzip and drop to/opt/gradle

Run

To build the Java project structure:

mkdir java-democd java-demo//opt/gradle/latest/bin/gradle init--type java-applicationtree# Generated directory structure ├──build.gradle├──gradle│└──wrapper│     ├──gradle-wrapper.jar│     └──gradle-Wrapper . properties├──gradlew├──gradlew.bat├──settings.gradle└──src    ├──main    │└──java    │     └──app.java

Build

Direct execution

java-demo$./Gradlew builddownloading https://services.gradle.org/distributions/ Gradle-4.9-bin.zip... ^c-------

This download will be slow because gradle-4.9-bin.zip has actually been downloaded, but it cannot be placed directly into the. Gradle directory because there is a hash string in the directory path

 ~/.gradle$ find ./-name gradle-*. zip   /wrapper/dists/gradle-4.4 -all/9br9xq1tocpiv8o6njlyu5op1/gradle-4.4 -all. zip   /wrapper/dists/gradle-4.6 -bin/4jp4stjndanmxuerzfseyb6wo/gradle-4.6 -bin. zip   /wrapper/dists/gradle-4.9 -bin/dv6yjbd5p4c085k06brhv9r3f/gradle-4.9 -bin. zip   /wrapper/dists/gradle-4.1 -all/bzyivzo6n839fup2jbap0tjew/gradle-4.1 -all. zip  

You can put the file in the project's Gradle/wrapper directory, and modify the Gradle-wrapper.properties, modify the following line

# distributionurl=https\://services.gradle.org/distributions/gradle-4.9-bin.zip distributionurl=gradle-4.9-bin. Zip

It will then be downloaded directly from the local

Update: After this process, if you change the gradle-wrapper.properties back again, the operation will be downloaded again, you can use another method:

Gradle library files are stored in the. GRADLE/CACHES/MODULES-2/FILES-2.1/Directory

Other commands that you can also run

# See how those are built. /Gradlew tasks# Run, Runs this project as a JVM application. /- Runs the unit tests. /gradlew Test

Load a separate JAR package

Add the Libs directory under the project and continue the jar package into the Libs directory

The Build.gradle configuration is as follows:

dependencies {Compile files (' Lib/ojdbc-14.jar ')}

Load the jar package for the entire directory

Create a folder in your own Gradle project named Libs (which you can define yourself, not necessarily the name), and copy your local jar package to this folder.

The Build.gradle configuration is as follows:

dependencies {Compile filetree (dir: ' Libs ', include:[' *.jar '])}
