Problem analysis

Developing Java The project will always encounter various problems that the dependencies cannot be loaded , In fact, the underlying principle of this loading dependency is to The wheels that others have developed can quickly help us solve the problems in the project . Here we need to introduce a series of jar package （jar The package can be understood as the required wheel ）. Therefore, the correct introduction of dependencies is the key .

Problem description

for instance ： The following distributed task scheduling dependency displays an error .

Solution

1、 First of all we need to Maven The central warehouse https://mvnrepository.com/ To find the corresponding dependency , View the dependent organization name 、 Whether the module name and version name are correct .
2、 stay Maven Some of the dependencies of the central warehouse cannot be found , So you get Githttps://github.com/ Open source websites like this look for , Download the corresponding dependency . Configured Maven Private clothes All my friends know what they depend on jar All the bags are made of groupId Store dependent for hierarchical folders jar package . Here, the corresponding jar The folder corresponding to the package creation can be placed in the private server .
3、 however , stay Git Not all the dependencies downloaded in jar Bag . So here we need to use IDEA Bring your own tools or use them directly Maven Can be installed .

GitHub The project in is compiled as jar Package for dependency introduction

1、 Use elastic-job-lite-spring-boot-starter For example , stay GitHub Search for relevant information in , Download to local .

2、 Use IDEA Self contained Maven Tool installation , If it's here IDEA The address of the private server is configured in ,IDEA The required dependencies will be directly placed in the corresponding location of the private server .

3、 After the above operation ,IDEA Will automatically GitHub The item in becomes the wheel required in the item and is placed in the corresponding private server folder .
