Question

如果在生成项目时使用“ LATEST”参数，则“ mvn clean install”命令会出错。应该使用此参数还是应在命令中提供最新版本？

mvn archetype:generate "-DarchetypeGroupId=com.sap.cloud.s4hana.archetypes" "-DarchetypeArtifactId=scp-cf-tomee" **"-DarchetypeVersion=LATEST**" "-DgroupId=com.sap.cloud.s4hana.examples" "-DartifactId=my-app" "-Dversion=1.0-SNAPSHOT"

错误是

Answer 1

版本2.7.1-SNAPSHOT不是发行版。外部不可用（Maven中央）。因此，您不能从Maven Central下载它。但是，2.6.1可用。这就是为什么它起作用。

请尝试使用RELEASE而不是LATEST，或者直接更好地使用已发布的版本。

还请检查settings.xml是否未指向内部快照关系服务器，然后删除.m2目录中的本地存储库。

Answer 2

您检查了网络配置吗？

我可以在日志中看到代理和未知主机错误。

构建项目时使用参数“ LATEST”不适用于“ mvn全新安装”
