无法从中央 Maven 存储库下载工件

Question

我正在测试一个简单的 Maven 项目，它需要下载 Jboss Java EE 7，但它无法做到这一点。错误信息是：

[ERROR] Failed to execute goal on project test: Could not resolve dependencies for project com.company:test:war:1.0-SNAPSHOT: Failure to find org.jboss.spec:jboss-javaee-7.0:jar:1.0.3.Final in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
[ERROR]

完整的 pom.xml 如下。是什么原因造成的？

Answer 1

尝试使用强制下载

mvn clean install -U

-U means force update of dependencies.

也存在伪影 here

Answer 2

工件在那里，但它不是 jar（默认值），它是 zip。此外，它似乎附加了一个分类器 (source-release)。如果这确实是你想要的依赖，你需要像这样指定你的依赖：

<dependency>
  <groupId>org.jboss.spec</groupId>
  <artifactId>jboss-javaee-7.0</artifactId>
  <version>1.0.3.Final</version>
  <type>zip</type>
  <classifier>source-release</classifier>
</dependency>

无法从中央 Maven 存储库下载工件
