Maven 错误和构建失败

Question

出现以下问题：打开 Ecipe 后，所有项目都用红色 X 签名。打开项目树，节点中没有错误符号。 Nothig 向我展示了导致错误的原因。我无法构建项目。最后，我为 Eclipse 创建了一个新工作区，从 SVN 签出项目，将它们作为 Maven 项目导入。 （有两个主要项目和几个子项目。） 还有两个项目显示红色 X，但未显示导致错误的原因。我试图在 Eclipse 中刷新、清理。我也无法毫无错误地构建其他项目，当然也不能构建有错误的项目。错误信息例如：

    [WARNING] Some problems were encountered while building the effective model for hu.bz.ikti.insurance:SAMCommon:jar:0.0.1-SNAPSHOT

对于错误的项目部分消息是：

    [ERROR] Failed to execute goal on project Service: Could not resolve dependencies for project hu.bz.ikti.insurance:Service:jar:0.0.1-SNAPSHOT: Failed to collect dependencies for [org.springframework:spring-context:jar:3.1.2.RELEASE (compile), org.springframework:spring-core:jar:3.1.2.RELEASE (compile), org.springframework:spring-beans:jar:3.1.2.RELEASE (compile), commons-dbcp:commons-dbcp:jar:1.4 (compile), postgresql:postgresql:jar:9.1-901-1.jdbc4 (compile), org.springframework:spring-tx:jar:3.1.2.RELEASE (compile), hu.bz.ikti.insurance:Model:jar:0.0.1-SNAPSHOT (compile), org.springframework:spring-orm:jar:3.1.2.RELEASE (compile), hu.bz.ikti:service-base:jar:0.0.1-SNAPSHOT (compile), org.springframework:spring-test:jar:3.1.2.RELEASE (compile), org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 (compile)]: Failed to read artifact descriptor for hu.bz.ikti.insurance:Model:jar:0.0.1-SNAPSHOT: Could not transfer artifact hu.bz.ikti.insurance:Model:pom:0.0.1-SNAPSHOT from/to ikti (https://fcd3.ikti.hu/artifactory/ext-release-local): Failed to transfer https://fcd3.ikti.hu/artifactory/ext-release-local/hu/bz/ikti/insurance/Model/0.0.1-SNAPSHOT/Model-0.0.1-SNAPSHOT.pom.

谁能帮帮我？

什么意思：

您正在尝试将快照版本 (Model-0.0.1-SNAPSHO‌​T.pom) 部署到仅发布版本的存储库 ext-release-local 中？ 选择一个快照存储库（例如 ext-snapshot-local）而不是一个发行版。

我应该更改我的 pom.xml 吗？如何？我不明白它以前怎么可能工作，但现在出现了这个编译问题。还有什么可以改变的？我没有改变任何意图。

我还注意到 .m2 文件夹下的 settings.xml 不存在。 Maven 确实出了点问题。

Answer 1

我偶然发现这篇文章有一个稍微不同的问题：我们尝试将工件 artifact-1.2.1.jar 部署到快照存储库并收到此错误：

org.artifactory.api.repo.exception.RepoRejectException: Cannot deploy file
'artifact-1.2.1.jar'. The repository 'repo_snapshot' rejected the resolution
of an artifact 'repo_snapshot:xxx/artifact/1.2.1/artifact-1.2.1.jar' due to 
conflict in the snapshot release handling policy.

我们的问题是 SNAPSHOT 不是工件文件名的一部分，因此将其重命名为 artifact-1.2.1-SNAPSHOT.jar 解决了这个问题。

正如@user944849 提到的，409 是重要的部分。 您正在尝试将快照版本 (Model-0.0.1-SNAPSHO‌​T.pom) 部署到仅限发布的存储库 ext-release-local，因此会发生冲突。 选择一个快照存储库（例如ext-snapshot-local）而不是一个发行版。
