https://mvnrepository.com/ maven 中央仓库
gradle可以轻松的完成Android项目对第三方jar包文件的依赖下载,再也不需要我们手动下载jar包,然后拷贝到lib目录,再手动添加依赖到项目中了,通过gradle可以快速的从中央仓库中下载jar文件,然后自动依赖到项目中
1. 搜索jar包
2.
例如输入:volley
3. 点击 标注 的版本号
4.
Maven 配置:
Gradle配置:
使用bat脚本下载jar包 方法:
1. 桌面新建文件夹“maven中央仓库jar包下载”
新建文件:download-jar-from-maven.bat
::使用DOS命令执行mvn命令:将pom.xml文件所依赖的jar包从maven中央仓库拷贝到本地
call mvn -f pom.xml dependency:copy-dependencies
@pause
2. 新建:pom.xml ,内容如下(下载 volley jar包为例):
<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<groupId>test.download</groupId>
<artifactId>test.download</artifactId>
<version>1.0.0</version>
<dependencies>
<dependency>
<groupId>com.mcxiaoke.volley</groupId>
<artifactId>library</artifactId>
<version>1.0.19</version>
</dependency>
</dependencies>
</project>
说明:上面 黄色标注 的内容就是从如下截图中拷贝过来的
也可以用如下写法:
<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<groupId>test.download</groupId>
<artifactId>test.download</artifactId>
<version>1.0.0</version>
<dependencies>
<dependency>
<groupId>com.mcxiaoke.volley</groupId>
<artifactId>library</artifactId>
<version>${volley-library-version}</version>
</dependency>
</dependencies>
<properties>
<volley-library-version>1.0.19</volley-library-version>
</properties>
</project>
3.双击“download-jar-from-maven.bat”运行就行了,其他不用管
脚本运行过程说明:
a. 首先创建本地maven仓库,默认的本机maven仓库 是在:C:Usersxxx.m2 epository ,第一次需要几分钟时间,耐心等待
b. 下载jar包。
最后截图:
脚本所在目录新生成“target”文件夹,所下载的jar文件在 targetdependency 目录下面,同时jar包在“C:Usersxxx.m2 epository...”下面也有一份(通过所下载的jar文件名结合Everything工具可以找到文件)
最后附:
swagger editor工具导出的pom.xml,其中所需jar包下载:
<?xml version="1.0" encoding="UTF-8"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <groupId>test.download</groupId> <artifactId>test.download</artifactId> <version>1.0.0</version> <dependencies> <dependency> <groupId>com.mcxiaoke.volley</groupId> <artifactId>library</artifactId> <version>1.0.19</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpcore</artifactId> <version>${httpcomponents-httpcore-version}</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient-android</artifactId> <version>${httpcomponents-httpclient-version}</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpmime</artifactId> <version>${httpcomponents-httpmime-version}</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>${google-code-gson-version}</version> </dependency> <dependency> <groupId>io.swagger</groupId> <artifactId>swagger-annotations</artifactId> <version>${swagger-annotations-version}</version> </dependency> </dependencies> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <httpcomponents-httpcore-version>4.4.4</httpcomponents-httpcore-version> <httpcomponents-httpmime-version>4.5.2</httpcomponents-httpmime-version> <httpcomponents-httpclient-version>4.3.3</httpcomponents-httpclient-version> <google-code-gson-version>2.6.2</google-code-gson-version> <swagger-annotations-version>1.5.8</swagger-annotations-version> </properties> </project>
