 Press Get from VCS. VCS stands for Version Control System. If Git is not installed, we need to download Git first. Meanwhile, open the Bookmap API GitHub, demo strategist project and copy the URL to clone the project. Git has been installed. Paste the URL and click Clone. Click the Git tab. You need to check out the branch, which corresponds with your Bookmap version. Mine is 7.3.0.33. Right click the 7.3 tag and check out. If you have no JDK installed, JDK stands for Java Development Kit, please install one. In this example, I already have the JDK 14 on my PC, but you may need to install it. We strongly recommend using Oracle Open JDK. You can use any version, the compatibility will be controlled by Gradle settings. Right click the build Gradle file and click the link Gradle project option if you have it. You can see the progress in the right bottom corner. Gradle is importing libraries and building the project. If you see no Bookmap API libraries in external libraries, right click the build Gradle and choose Reload from disk. Please notice, the imported libraries have slightly different versions, not 7.3.0.33 like my Bookmap version. We need to change it. Let's open the build Gradle again. Since we are using idea ID in this example, please comment with double slashes the line that refer to Eclipse ID and add the apply plugin idea line. Also add the java.properties. For Bookmap release version, 7.3.0.0 here means an official release. So you need to change the maven repository URL from develop to releases. Then change the libraries versions to your Bookmap version. Gradle load changes button should appear. Press it to update the project.
