Maven依賴沖突解決之exclusions

1.背景

作為java生態(tài)下開發(fā)者，往往需要使用大量線程的第三方庫，一般都是以jar包形式存在。

maven作為事實上主流的jar包依賴管理工具，Idea和Eclipse都支持創(chuàng)建maven工程來管理jar包依賴。

使用maven進(jìn)行jar包依賴管理時，maven會自行管理jar包及其依賴鏈條，但往往會遇到依賴沖突問題，這時候就可以嘗試使用exclusion來進(jìn)行依賴管理。

2.解決方式

場景

假如hadoop集群中hadoop版本是3.2.1，這時候為了保證程序能夠順利操作hadoop，需要引入hadoop-client的3.2.1版本。但這里也可以看到，spark-core_2.12內(nèi)部也有對hadoop-client的依賴，而且版本是低版本的2.7.4，這時候往往就會產(chǎn)生沖突或者未知錯誤。所以需要使用exclusions做依賴排除。

解決方式

使用exclusions來對某一個第三方庫引入的依賴jar包做排除

Maven解決依賴沖突總結(jié)

如果存在jar包的依賴沖突，在項目啟動時總是報類似這樣的錯：NoSuchMethodError、ClassNotFoundException、成員變量找不到等等。真的很讓人不好受。

Maven采用的是“最近獲勝的策略”來處理依賴的沖突，即如果一個項目最終依賴于相同artifact的多個版本，在依賴樹中離項目最近的那個版本將被使用。讓我們來看看一個實際的例子。

實例分析

我們有一個web應(yīng)用resolve-web，該工程依賴于project-A和project-B，project-A依賴于project-common的1.0版本并調(diào)用其中的sayHello()方法。project-B依賴于project-C，而project-C又進(jìn)一步依賴于project-common的2.0版本并調(diào)用其中的sayGoodBye()方法。project-common的1.0和2.0版本是不同的，1.0中之包含sayHello()方法，而2.0中包含了sayHello()和sayGoodBye()兩個方法。整個項目的依賴關(guān)系如下圖：

根據(jù)Maven的最近原則依賴機(jī)制，resolve-web將同時依賴于project-common的1.0和2.0版本，這就造成了依賴沖突。而根據(jù)最近獲勝策略，Maven將選擇project-common的1.0版本作為最終的依賴。這和Gradle不同，Gradle在默認(rèn)情況下將選擇最新的版本作為獲勝版本。而對于Maven，由于proejct-common的1.0版本比2.0版本在依賴樹中離resolve-web更近，故1.0版本獲勝。在resolve-web中執(zhí)行"mvndependency:tree-Dverbose"可以看到resolve-web的依賴關(guān)系：

[INFO]resolve-web:resolve-web:war:1.0-SNAPSHOT

[INFO]+-junit:junit:jar:3.8.1:test

[INFO]+-project-B:project-B:jar:1.0:compile

[INFO]|\-project-C:project-C:jar:1.0:compile

[INFO]|\-(project-common:project-commmon:jar:2.0:compile-omittedforconflictwith1.0)

[INFO]+-project-A:project-A:jar:1.0:compile

[INFO]|\-project-common:project-commmon:jar:1.0:compile

[INFO]\-javax.servlet:servlet-api:jar:2.4:provided

由上可知，project-common:project-commmon:jar:2.0被忽略掉了。此時在resolve-web的war包中將只包含project-common的1.0版本，于是問題來了。由于project-common的1.0版本中不包含sayGoodBye()方法，而該方法正是project-C所需要的，所以運行時將出現(xiàn)“NoSuchMethodError”。

解決辦法

方法1：顯式加入對project-common2.0版本的依賴。先前的2.0版本不是離resolve-web遠(yuǎn)了點嗎，那我們就直接將它作為resolve-web的依賴，這不就比1.0版本離resolve-web還近嗎？在resove-web的pom.xml文件中直接加上對project-common2.0的依賴

dependency

groupIdproject-common/groupId

artifactIdproject-commmon/artifactId

version2.0/version

/dependency

方法2：resolve-web對project-A的dependency聲明中，將project-common排除掉。在resolve-web的pom.xml文件中修改對project-A的dependency聲明

dependency

groupIdproject-A/groupId

artifactIdproject-A/artifactId

version1.0/version

exclusions

exclusion

groupIdproject-common/groupId

artifactIdproject-commmon/artifactId

/exclusion

/exclusions

/dependency

此時再在resolve-web中執(zhí)行"mvndependency:tree-Dverbose"，如下：

......

[INFO]resolve-web:resolve-web:war:1.0-SNAPSHOT

[INFO]+-junit:junit:jar:3.8.1:test

[INFO]+-project-B:project-B:jar:1.0:compile

[INFO]|\-project-C:project-C:jar:1.0:compile

[INFO]|\-project-common:project-commmon:jar:2.0:compile

[INFO]+-project-A:project-A:jar:1.0:compile

[INFO]\-javax.servlet:servlet-api:jar:2.4:provided

......

這樣的話，就可以完美解決沖突了。

命令分析

這里我們對我們執(zhí)行的命令做一個簡單的說明。

mvndependency:tree-Dverbose-Dincludes=groupId:artifactId

1、第一部分mvndependency:tree是maven依賴的分析命令，作用是對我們的項目的依賴進(jìn)行分析，并輸出項目依賴樹

2、第二部分-Dverbose的作用是添加了verbose一個環(huán)境變量，起的作用是在分析項目依賴時輸出明細(xì)，這樣項目中依賴的所有3、引用都會被輸出出來，包含了所有的間接引用，會有很多很多，我們只需要我們要找的，所以就需要第三個參數(shù)了第三部分-Dincludes=groupId:artifactId的作用就是進(jìn)行過濾，只包含我們想要的依賴的依賴時，排除掉其它不需要的，依賴樹的所有葉子節(jié)點就是我們的找的依賴包。其中的groupId和artifactId可以只填寫一個，為了保證準(zhǔn)確性，一般都會填兩個（填寫時不包括尖括號）。

小試牛刀

執(zhí)行命令分析下，項目的jar包的依賴情況，只過濾并分析spring框架的jar包依賴樹情況，使用的命令如下：

mvndependency:tree-Dverbose-Dincludes=org.springframework:

在新引入的項目jar包中，發(fā)現(xiàn)其再次引入了spring的相關(guān)包并且該spring包的層級屬于第二層級，實際已有的spring的包處在第三或者第四層級，根據(jù)就近原則，低版本的3.2.5的jar包覆蓋了高版本的jar包，導(dǎo)致出現(xiàn)找不到某變量的異常。剔除這些jar包如下配置：
