Original GitHub issue: https://github.com/nektos/act/issues/584

It seems Java use homedir from nsswitch, so this behavior breaks java build tools like Apache Maven & Gradle which use user.home system property to resolve configuration. E.g. actions/setup-java@v1 writes settings.xml to /github/home/.m2/settings.xml (nodejs resolves using $HOME) but maven later tries to lookup it from /root/.m2/settings.xml (jre resolves using nss).

Act version

act version 0.2.20

Expected behaviour

act to set same home dir in both $HOME and /etc/passwd.

Actual behaviour

$HOME is set to /github/home but /etc/passwd contains root:x:0:0:root:/root:/bin/bash.

Workflow and/or repository

workflow

name: t
on:
  push:
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-java@v1
        with:
          java-version: 11
      - run: |
          echo 'public class Test {
            public static void main(String[] args) {
              System.out.println("user.home: " + System.getProperty("user.home"));
            }
          }' >Test.java
          javac Test.java
          java Test
          id
          getent passwd $(id -u)
          echo "\$HOME=$HOME"

Steps to reproduce

Run act with workflow above
