解決screw Maven插件方式運(yùn)行時(shí)，在編譯打包時(shí)跳過執(zhí)行的問題

問題描述

在引入screw 進(jìn)行數(shù)據(jù)庫文檔生成，并且使用Maven插件方式運(yùn)行時(shí)，在執(zhí)行項(xiàng)目打包時(shí)，會自動運(yùn)行該插件。導(dǎo)致在不需要重新生成數(shù)據(jù)庫文檔時(shí)，也會去生成數(shù)據(jù)庫文檔。并且通常數(shù)據(jù)庫文檔生成是基于開發(fā)環(huán)境的數(shù)據(jù)庫的，對于非開發(fā)環(huán)境的自動打包處理環(huán)境，往往是無法訪問開發(fā)環(huán)境數(shù)據(jù)庫，這也會導(dǎo)致項(xiàng)目的打包出錯(cuò)的問題。出錯(cuò)信息如下:

調(diào)研

通常的對于Maven插件跳過使用，我們只需要找插件的對應(yīng)的skip 參數(shù)，然后在打包時(shí)通過-D 參數(shù)來修改這個(gè)參數(shù)即可，但通過閱讀這個(gè)插件的源碼，并且開啟Maven的-X 參數(shù)執(zhí)行，都沒有在這個(gè)插件中找到skip 參數(shù)。

插件啟動執(zhí)行代碼位置：https://gitcode.net/mirrors/pingfangushi/screw/-/blob/master/screw-maven-plugin/src/main/java/cn/smallbun/screw/maven/plugin/mojo/RunDocMojo.java

通過查看代碼得知，插件的默認(rèn)觸發(fā)執(zhí)行的Phase 是COMPILE，因此解決的思路就有了。

解決方案

方案1

注釋掉插件引入代碼，在開發(fā)環(huán)境需要手動執(zhí)行的時(shí)候，再放開注釋。

方案2

不再寫死配置的Phase ，而是指定一個(gè)變量，由運(yùn)行Maven命令時(shí)，通過參數(shù)-D 傳入正確的Phase ，而不需要執(zhí)行的時(shí)候，傳入一個(gè)不存在的Phase 或者干脆不傳入Phase 即可。

Maven 運(yùn)行的方法：

不需要運(yùn)行

clean package -Dmvn.screw.skip=none -f pom.xml 或者 clean package -f pom.xml

需要運(yùn)行

clean package -Dmvn.screw.skip=compile -f pom.xml

單獨(dú)運(yùn)行：

screw:run -f pom.xml
