public class ReadMavenProperties {
    public static void main(String[] args) {
        Properties properties = new Properties();
        try {

            properties.load(inputStream);
        } catch (IOException e) {

        }

        // 获取属性值
        String version = properties.getProperty("project.version");
        String buildTime = properties.getProperty("build.time");

        System.out.println("Version: " + version);
