使用maven怎么生成一個(gè)可執(zhí)行的jar包

今天就跟大家聊聊有關(guān)使用maven怎么生成一個(gè)可執(zhí)行的jar包，可能很多人都不太了解，為了讓大家更加了解，小編給大家總結(jié)了以下內(nèi)容，希望大家根據(jù)這篇文章可以有所收獲。

站在用戶的角度思考問題，與客戶深入溝通，找到綿陽網(wǎng)站設(shè)計(jì)與綿陽網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗(yàn)，讓設(shè)計(jì)與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個(gè)性化、用戶體驗(yàn)好的作品，建站類型包括：成都做網(wǎng)站、成都網(wǎng)站設(shè)計(jì)、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、主機(jī)域名、網(wǎng)站空間、企業(yè)郵箱。業(yè)務(wù)覆蓋綿陽地區(qū)。

從pom的xsi中可以打開描述pom的schema:

可以看到pom中，project的結(jié)構(gòu)：

默認(rèn)的mvn install生成的jar是不帶主類入口的，需要在maven-compile-plugin中設(shè)置主類，

執(zhí)行mvn install:

在target目錄中，發(fā)現(xiàn)jar包已經(jīng)生成：

用java decompiler，可以看到manifest中已經(jīng)加入了MainClass：
