I am getting the following error when i try to compile using mvn.

./mvnw clean test

Okay, seems like we need to use correct proxy. Here is a small startup-script that installs dependencies using maven 3.9.9! Same can of course be done using mvnw, this is just simplified (and not yet fully optimised, more a proof of concept):

#!/bin/sh

version=3.9.9
url="https://dlcdn.apache.org/maven/maven-3/${version}/binaries/apache-maven-${version}-bin.tar.gz"
echo $url
wget $url

sleep .4

tarFile="apache-maven-${version}-bin.tar.gz"
echo $tarFile
sudo tar -xvf $tarFile -C /opt/

export PATH=/opt/apache-maven-${version}/bin:$PATH
echo -e "\nPATH=\"/opt/apache-maven-${version}/bin:\$PATH\"" >> ~/.profile

mkdir -p ~/.m2 && cat > ~/.m2/settings.xml <<EOF
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                              https://maven.apache.org/xsd/settings-1.0.0.xsd">
</settings>
EOF

sed -i '/<\/settings>/ i\
  <proxies>\
    <proxy>\
      <id>defaultProxy</id>\
      <active>true</active>\
      <protocol>http</protocol>\

mvn dependency:go-offline -X

I have the same issue, oddly if I use your proxy fix in the environment setup and use the interactive terminal there it does fix the issue. But when I actually come to use the environment it fails in the same way with network connectivity issues in the startup script even though I can see its running the same sed cmd etc.

Thank you for your reply!

How can we make it work with gradle?

Thanks, this was very helpful!

Anyone know how to make it work with a private maven repo (github packages)?

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:3.8.1:go-offline (default-cli) on project my-project: org.eclipse.aether.resolution.DependencyResolutionException: Failed to read artifact descriptor for com.mycompany.myproject:jar:version: Could not transfer artifact descriptor for com.mycompany.otherproject:jar:version from/to github (https://maven.pkg.github.com/mycompany/*): authentication failed for https://maven.pkg.github.com/..., status: 401 Unauthorized -> [Help 1]

Codex has access to our github repositories, but not our github packages. Anyone know how to solve that?

To answer my own question, the key was to add the repository to settings.xml and configure the token using Codex secrets.

cat > ~/.m2/settings.xml <<EOF
<settings>
  <proxies>
    <proxy>
      <id>codexProxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy</host>
      <port>8080</port>
    </proxy>
  </proxies>

...

        <repository>
          <id>github</id>
          <url>https://maven.pkg.github.com/mycompany/*</url>
          <snapshots>
            <enabled>true</enabled>
          </snapshots>
        </repository>

...

  <servers>
    <server>
      <id>github</id>
      <username>\${env.GITHUB_ACTOR}</username>
      <password>\${env.GITHUB_TOKEN}</password>
    </server>
  </servers>

</settings>
EOF

Then configure GITHUB_ACTOR and GITHUB_TOKEN in Codex environment secrets.

This is my solution using mirroring and preloading the plugins -

#!/bin/bash
set -e

echo "[INFO] Installing Maven..."
apt update && apt install -y maven curl unzip

echo "[INFO] Setting up Maven to use local repository only..."
mkdir -p /root/.m2

cat <<EOF > /root/.m2/settings.xml
<settings>
  <mirrors>
    <mirror>
      <id>local-repo</id>
      <mirrorOf>*</mirrorOf>
      <url>file:///root/.m2/repository</url>
    </mirror>
  </mirrors>
</settings>
EOF
