項(xiàng)目用mvn exec:exec指令來(lái)啟動(dòng)server, 工作中需要調(diào)式server初始化的過(guò)程, 很容易想到mvnDebug, 但是發(fā)現(xiàn)設(shè)置的斷點(diǎn)都沒(méi)有hit, 反復(fù)調(diào)式多次都是如此,折騰了1個(gè)多小時(shí), 突然看到stackoverflow 上有人說(shuō)exec:exec是獨(dú)立進(jìn)程模式, mvnDebug的一些debug選項(xiàng)都被append到了父進(jìn)程了. idea設(shè)置斷點(diǎn)就然并卵了.
知道了問(wèn)題所在解決就容易了, 只要修改pom.xml, 然后直接mvn exec:exec就能正常調(diào)式了

總結(jié)就是exec:exec是要獨(dú)立一個(gè)新進(jìn)程來(lái)執(zhí)行程序的, exec:java就相反, 其實(shí)用mvnDebug + exec:java也是理論可行的
