maven 生成 pom 文件 [英] maven generating pom file

问题描述

我使用 maven 3.0.3 并尝试为第三方 jar 生成 pom，如下所示:

I use maven 3.0.3 and have tried to generate pom for third-party jar like this:

mvn install:install-file -Dfile=cobra.jar -DgroupId=com.cobra-DartifactId=cobra -Dversion=0.98.4 -Dpackaging=jar -DgeneratePom=true

mvn install:install-file -Dfile=cobra.jar -DgroupId=com.cobra -DartifactId=cobra -Dversion=0.98.4 -Dpackaging=jar -DgeneratePom=true

根据下面的链接，它应该生成正确的 pom.xml 并在 repo 中安装工件.http://maven.apache.org/plugins/maven-install-plugin/examples/generic-pom-generation.html

According to link below it should generate proper pom.xml and install artifact in the repo. http://maven.apache.org/plugins/maven-install-plugin/examples/generic-pom-generation.html

同时，它返回这样一个错误:

Meanwhile, it returns such a error:

[ERROR] 您指定的目标需要一个项目来执行，但有在此目录 (D:cobra-0.98.4lib) 中没有 POM.请验证您从正确的目录调用 Maven.-> [帮助 1]

[ERROR] The goal you specified requires a project to execute but there is no POM in this directory (D:cobra-0.98.4lib). Please verify you invoked Maven from the correct directory. -> [Help 1]

为什么它应该生成 pom.xml 而要求 pom.xml?

Why is it asking for pom.xml while it should generate pom.xml?

推荐答案

这是一个老问题，但对我来说是几分钟的严重 PITA，所以我想我会分享:

This is an old question, but was a serious PITA for me for a few minutes, so I thought I'd share:

我刚刚遇到了这个问题，我认为这个问题可能与平台有关.真正的提示是 Cyril 的答案中的解决方案没有按预期工作:尽管我指定了 -DgroupId=com.xyz 和 -DartifactId=whatever命令行和POM文件中的相应条目，jar安装在com/whatever下的本地repo中.

I just ran into this problem, and I believe that the issue is probably platform-dependent. The real tip-off was that the solution from Cyril's answer wasn't working as expected: despite my specification of -DgroupId=com.xyz and -DartifactId=whatever on the command-line and the corresponding entry in the POM file, the jar was installed in the local repo under com/whatever.

这让我尝试引用命令行参数，以及像这样格式化命令行的最终正确结果(删除 POM 文件后):

This led me to experiment with quoting command-line arguments, and the eventual correct result from formatting the command-line like this (after deleting the POM file):

mvn install:install-file "-Dfile=cobra.jar" "-DgroupId=com.cobra" "-DartifactId=cobra" "-Dversion=0.98.4" "-Dpackaging=jar" "-DgeneratePom=true"

有些引用无疑是多余的，但总比抱歉好，对吧?我碰巧在这台计算机上运行 Vista，如果这个问题特定于这个操作系统版本，我不会感到惊讶......顺便说一下，这是 Maven v3.0.4.

Some of the quoting is doubtless redundant, but better safe than sorry, right? I happen to be running Vista on this computer, and would not be surprised if this problem were specific to this OS version...by the way, this was with Maven v3.0.4.
