Maven

Question

我正在尝试编译一个名为 web-server 的 Maven 项目，该项目依赖于指定依赖版本范围内的 search-client [2.0,3.0]。然而，由于存储库中“指定范围内没有版本可用于 > com.test.search:search-client:jar:[2.0,3.0)”，编译失败。

这些是我正在执行的步骤：

进行更改并在本地构建搜索客户端

这会在我的本地 m2 存储库中为此客户端 pom 构建一个 2.0-SNAPSHOT jar。

尝试构建依赖于上述的网络服务器

这不会编译并给出以下错误：

[ERROR] Failed to execute goal on project common: Could not resolve dependencies for project com.test.web:common:jar:2.0-SNAPSHOT: Failed to collect dependencies at com.test.search:search-client:jar:[2.0,3.0): No versions available for com.test.search:search-client:jar:[2.0,3.0) within specified range -> [Help 1]

2.0-SNAPSHOT不在[2.0,3.0)吗？我被严格要求不要增加版本。另外，在这样的maven依赖设计中，如何进行本地开发？

请帮忙，我卡住了！

非常感谢:)

Answer 1

根据POM Reference, Version Order Specification：

"1-snapshot" < "1" < "1-sp" (qualifier padding)

2.0-SNAPSHOT 比 2.0 少，它总是在 Maven 中：快照版本是下一个发布版本的 pre-versions。

所以，不，2.0-SNAPSHOT 不在 [2.0,3.0) (2.0 <= x < 3.0) 中。 (1,3.0) (1 < x < 3.0) 应该做到。

而且，您的 Web 服务器 POM 中有一个拼写错误：

            <version>_____3,0)</version>

Maven - 无法在本地解决版本范围的 Maven 依赖关系

Maven - Unable to resolve maven dependency locally for version range
