Maven项目转Gradle项目
将Maven项目拷贝到C盘用户目录下(其他目录没试过),然后在cmd窗口中,进入Maven项目根目录下,执行gradle init –type pom 命令(可能需要在电脑上提前安装好Gradle插件),Maven项目下就会自动生成Gradle对应的配置。此时项目既是Gradle项目又是Maven项目。可用IDEA等IDE直接导入该项目。
用Gradle工具打Jar包步骤
- 首先,打开IDE的右侧边栏Gradle,找到:对应module -> Tasks ->other -> release,双击该task,就会执行。执行完成后,会在对应Module -> build ->libs ->lib下生成一堆jar,这些都是打驱动Jar要用到的。(这是我猜测的,嘿嘿)
- 然后,打开IDE的右侧边栏Gradle,找到:对应Module -> Tasks ->other -> makeAndroidJar,双击该task,就会执行。执行完成后,会在对应Module -> build ->libs下生成一个android.jar,该jar就是最后的驱动Jar。
- makeAndroidJar task主要是将项目本身和打ethereum driver所需的所有依赖(release task 生成的jar)统一打成一个Jar;
- 打Jar的逻辑详见makeAndroidJar task、release task 及其它相关task;
