sbt 未解决的依赖问题

Question

我正在尝试运行这个 sbt 项目（基于 play framework 2.4） https://github.com/pac4j/play-pac4j-scala-demo

我正在使用“激活器运行”命令。我的激活器版本是 1.3.6

我确实在 sbt 使用的默认 maven 存储库中看到了该项目。但是，上面的日志似乎表明它没有找到。

https://repo1.maven.org/maven2/com/nimbusds/nimbus-jose-jwt/

我尝试清除 ivy 缓存目录。但是，这似乎没有帮助。

输出

Answer 1

问题出在[4.0,]。

Ivy Version Matchers 不支持[4.0,]，在this issue 中报告。

在Maven Version Range 中没有明确描述但似乎接受[4.0,]。

我觉得应该是[4.0,)，意思是version >= 4.0，都被ivy和maven接受了。

使用sbt-dependency-graph插件，可以看到问题出在com.nimbusds:oauth2-oidc-sdk:5.0-alpha2。

[info]   +-org.pac4j:pac4j-oidc:1.8.0-SNAPSHOT
[info]   | +-com.nimbusds:oauth2-oidc-sdk:5.0-alpha2
...
[info]   | | +-com.nimbusds:nimbus-jose-jwt:[4.0,] (error: not found) (evicted by: 4.0) 

查看这个项目的pom.xml，你会发现

<dependency>
  <groupId>com.nimbusds</groupId>
  <artifactId>nimbus-jose-jwt</artifactId>
  <version>[4.0,]</version>
</dependency>

也许您可以给他们一个issue 以将[4.0,] 替换为[4.0,)。

解决方法是在com.nimbusds:oauth2-oidc-sdk:5.0-alpha2 被sbt 缓存之后编辑~/.ivy2/cache/com.nimbusds/oauth2-oidc-sdk/ivy-5.0-alpha2.xml。

换行

<dependency org="com.nimbusds" name="nimbus-jose-jwt" rev="[4.0,]" force="true" conf="compile->compile(*),master(compile);runtime->runtime(*)"/>
                                                      ~~~~~~~~~~~~

到rev="[4.0,)" 并再次运行sbt。
