Question

我試圖在Docker中運行Maven。

所以我從她https://hub.docker.com/_/maven/拉圖像。

docker pull maven 

然而，當我運行它：

docker run maven 

我得到：

[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] 

我沒有與Maven經驗，所以我不明白是什麼導致這個問題。

Docker容器只安裝了Maven，但它沒有運行它，所以我不明白Maven如何拋出錯誤。

你需要在目標選項卡中定義'clean install'作爲maven後clicbuild。
