Maven包沖突排查思路

maven 樹

指令：mvn dependency:tree

結果：groupId:artifactId:version

指令參數

-Dverbose參數：加上後會顯示更加詳細的資訊；

-Dincludes參數/-Dexcludes參數：加上後包含/排除指定包；【格式：groupId:artifactId:version 可以不寫全】

eg：mvn dependency:tree -Dverbose -Dincludes=commons-collections

[INFO] com.jd.union.jingtiao:union-jingtiao-web:war:1.0-SNAPSHOT
[INFO] +- com.jd.union.jingtiao:union-jingtiao-service:jar:1.0-SNAPSHOT:compile
[INFO] |  +- com.jd.union.jingtiao:union-jingtiao-res:jar:1.0-SNAPSHOT:compile
[INFO] |  |  \- (commons-collections:commons-collections:jar:3.2.2:compile - omitted for duplicate)
[INFO] |  \- (commons-collections:commons-collections:jar:3.2.2:compile - omitted for duplicate)
[INFO] \- commons-collections:commons-collections:jar:3.2.2:compile
