问题

如何在mvn构建中通过环境变量设置settings.xml的路径？

我尝试过：

export MAVEN_OPTS="-s /tmp/settings.xml";

或者

export MAVEN_OPTS="--settings /tmp/settings.xml";

但是都不起作用。

我需要这样做，因为我无法修改构建命令。

英文:

How can I set the path of the settings.xml from environment variable in a mvn build?

I have tried:

export MAVEN_OPTS=&quot;-s /tmp/settings.xml&quot;

export MAVEN_OPTS=&quot;--settings /tmp/settings.xml&quot;

but it not works.

I need it, because I cannot modify the build command.

你可以在你的gitlab-ci构建脚本中尝试像这样做，就在调用mvn之前：
（详见https://maven.apache.org/configure.html#mvn-maven-config-file）

mkdir -p .mvn && echo "-s /tmp/settings.xml" >> .mvn/maven.config

这不会修改仓库，只会在运行构建作业的本地检出中添加一个文件。

从Maven 4开始，这也应该可以工作：

export MAVEN_ARGS="-s /tmp/settings.xml"

详见https://maven.apache.org/configure.html#maven_args-environment-variable

英文:

You could try something like this in your gitlab-ci build script, just before calling mvn:
(see https://maven.apache.org/configure.html#mvn-maven-config-file)

mkdir -p .mvn &amp;&amp; echo &quot;-s /tmp/settings.xml&quot; &gt;&gt; .mvn/maven.config

This does not modify the repo, only adds a file to the local checkout within the running build job.

Starting with Maven 4 this should also work:

export MAVEN_ARGS=&quot;-s /tmp/settings.xml&quot;
