Introduction to Mill SCALALIB framework in the Java class library

Introduction to Mill SCALALIB framework in the Java class library Mill Scalalib is a collection tool and class library set for SCALA language design.Its goal is to provide simple and efficient construction methods to simplify the management and construction process of the Scala project.Mill SCALALIB also provides many useful methods and methods, so that developers can easily write high -quality code. The characteristics of Mill SCALALIB include: 1. Easy to use: Mill provides a simple and easy -to -understand construction DSL (specific language), making the construction project very simple.Developers only need to write a simple script to define the construction process of the project. 2. High performance: The construction process of Mill is very fast, which can effectively use system resources to improve the construction speed.Mill uses a way to build an incremental construction, only to re -build a change, without having to repeatedly build the entire project. 3. Construction of concurrent: Mill can build multiple projects in parallel to significantly reduce the construction time.It supports the construction of cache and incremental construction to minimize redundant construction steps. 4. Rich class libraries: Mill Scalalib contains many useful classes and methods, which encapsulate common tasks and operations, such as files and path processing, network requests, JSON analysis, etc.These class libraries can help developers write complex applications easier. Below is a simple example of using Mill SCALALIB to show how to use Mill to build a basic SCALA project. First, you need to install the Mill to build a tool.Then, create a folder called "MyProject", and create a file called "Build.sc" in this folder. The content of the build.sc file is as follows: scala import mill._ object myproject extends ScalaModule { def scalaVersion = "2.13.6" def ivyDeps = Agg( ivy"org.scala-lang.modules::scala-xml:1.3.0", ivy"org.scalatest::scalatest:3.2.10" ) def compile = T{ println("Compiling...") // The task of compiling code } def test = T{ println("Running tests...") // The task of running the test } } In the build.sc file, you can specify the scala version and project dependencies.In the above examples, the project depends on the SCALA XML module and the Scalatemt library. Use the terminal to enter the project folder and run the following command: shell $ mill myproject.compile This will compile the code of the project.You can also run the following command to run the test: shell $ mill myproject.test The Mill SCALALIB framework provides a simple and efficient way to build and manage the SCALA project.By using Mill, developers can build projects more quickly and use rich class libraries to write high -quality code.Whether it is a small project or a large project, Mill SCALALIB is a choice worth considering. I hope this article has a preliminary understanding of the Mill Scalalib framework and gives you a clearer understanding of how to use it.If you are interested, you can continue to learn and explore more functions and features of the framework.
