The best practice of SBT Framework Construction Java Library

The best practice of SBT Framework Construction Java Library Overview SBT (SIMPLE Build Tool) is a SCALA -based construction tool that is used to manage the tasks such as dependence, compilation code and running testing of projects.For Java developers, using the SBT framework to build a Java class library is an efficient way. This article will introduce the best practice to build a JAVA library with the SBT framework. step The following are the steps to build a Java library with SBT: 1. Install SBT First of all, you need to install SBT, you can download and install SBT from the official website.After the installation is completed, enter the "SBT" command in the command line. If the version of the SBT is displayed, the installation is successful. 2. Create an SBT project Use SBT to create a new project, you can enter the folder that needs to be created in the command line, and then execute the following command: sbt new sbt/scala-seed.g8 This will use the SBT template to create a new SCALA project, and the project needs to be converted into the Java project. 3. Configuration project In the created project, Java support is needed.Add the following configuration in the "Build.sbt" file in the project root directory: scala scalaVersion := "2.13.8" libraryDependencies += "org.scala-lang.modules" %% "scala-xml" % "2.0.1" javacOptions ++= Seq("-source", "1.8", "-target", "1.8") The above configuration specifies the SCALA version, dependency library and Java compilation options used by the project. 4. Create a java library Create a Java file in the project's "SRC/main/Java" directory, which can be a single or multiple classes.Add the required Java code in the class file. 5. Compile and run Enter the following commands in the command line to compile the project: sbt compile After the compilation is completed, you can use the following command to run the unit test in the project: sbt test Summarize Through the above steps, you can use the SBT framework to build a Java class library.The use of SBT can manage the tasks of dependence, compilation and operation testing of projects, which greatly improves the development efficiency of the project.It is hoped that the best practice described in this article will help developers using SBT to build a Java library.
