没有为此构建指定目标。

Question

我正在尝试在 Docker 中运行 Maven。

所以我从她https://hub.docker.com/_/maven/ 那里提取了图片。

docker pull maven

但是，当我运行它时：

docker run maven

我明白了：

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]

我没有使用 Maven 的经验，所以我不明白是什么导致了这个问题。

Docker 容器只安装了 Maven，但它没有运行它，所以我不明白 Maven 是如何抛出错误的。

Answer 1

点击build as maven后，您需要在目标选项卡中定义clean install。
