本地maven依赖崩溃?什么原因导致依赖版本不同于pom?

在一个项目中,它有如下maven模块:

A -> A1, A2, module A has 2 sub modules A1 and A2.
A1 -> A2, module A1 has A2 as its dependency

字符串
在A1中运行mvn dependency:tree,显示以下结果:

[INFO] +- A2:jar:1.0.0-SNAPSHOT:compile
[INFO] |  +- co.elastic.clients:elasticsearch-java:jar:8.2.3:compile
[INFO] |  |  +- org.elasticsearch.client:elasticsearch-rest-client:jar:7.6.2:compile
[INFO] |  |  |  +- org.apache.httpcomponents:httpclient:jar:4.5.13:compile
[INFO] |  |  |  +- org.apache.httpcomponents:httpcore:jar:4.4.14:compile
[INFO] |  |  |  +- org.apache.httpcomponents:httpasyncclient:jar:4.1.4:compile
[INFO] |  |  |  \- org.apache.httpcomponents:httpcore-nio:jar:4.4.14:compile
[INFO] |  |  +- com.google.code.findbugs:jsr305:jar:3.0.2:compile
[INFO] |  |  \- org.eclipse.parsson:parsson:jar:1.0.0:compile
[INFO] |  +- jakarta.json:jakarta.json-api:jar:1.1.6:compile


在A2中运行相同的命令,显示以下结果:

[INFO] +- co.elastic.clients:elasticsearch-java:jar:8.2.3:compile
[INFO] |  +- org.elasticsearch.client:elasticsearch-rest-client:jar:7.6.2:compile
[INFO] |  |  +- org.apache.httpcomponents:httpclient:jar:4.5.13:compile
[INFO] |  |  +- org.apache.httpcomponents:httpcore:jar:4.4.14:compile
[INFO] |  |  +- org.apache.httpcomponents:httpasyncclient:jar:4.1.4:compile
[INFO] |  |  \- org.apache.httpcomponents:httpcore-nio:jar:4.4.14:compile
[INFO] |  +- com.google.code.findbugs:jsr305:jar:3.0.2:compile
[INFO] |  \- org.eclipse.parsson:parsson:jar:1.0.0:compile
[INFO] +- jakarta.json:jakarta.json-api:jar:2.0.1:compile


jakarta.json-api在A1中有错误的版本,提示它是从A2中包含的。但是,在A2中,提示显示它没有version 1.1.6 jakarta.json-api
这是git bash CLI的结果,没有使用任何工具。这是我第一次遇到这样的maven依赖行为。所有命令都在mvn clean之后运行
这是A2 pom:

我使用了一个GUI工具来解析A1 pom.xml,它显示了:

A2: 1.0.0-SNAPSHOT[compile]
- elasticsearch-java: 8.2.3[compile](omitted for conflict with 2.0.1)
- - jakarta.json-api: 1.1.6 [compile]
- - parsson: 1.0.0[compile]
- - - jakarta.json-api: 1.1.6 [compile](omitted for conflict with 2.0.1)
- jakarta.json-api: 1.1.6 [compile](omitted for conflict with 2.0.1)
jakarta.json-api: 2.0.1 [compile]


并使用该工具解析A2 pom.xml:

elasticsearch-java: 8.2.3[compile]
- jakarta.json-api: 1.1.6 [compile](omitted for conflict with 2.0.1)
- parsson: 1.0.0[compile]
- - jakarta.json-api: 1.1.6 [compile](omitted for conflict with 2.0.1)
jakarta.json-api: 2.0.1 [compile]

Maven基于最近的定义规则解决冲突依赖项。在您的案例中,A2应该使用A作为父依赖项来解决。Maven将使用与声明依赖项的项目最接近的版本。您可以显式控制提供直接依赖项的版本或在其中一个依赖项上写入例外。
