Add support for multiple servers.

[drewctaylor]

Currently, as I understand it, the user may specify only one server, as follows:

- name: Setup Java.
  uses: actions/setup-java@v1
  with:
    java-version: 1.8
    server-id: value-of-server-id
    server-username: SERVER_USERNAME
    server-password: SERVER_PASSWORD

Which produces the following xml in the settings.xml file:

<server>
  <id>value-of-server-id</id>
  <username>value-of-server-username</username>
  <password>value-of-server-password</password>
</server>

However, it would be useful to be able to specify more than one server. For example, this yaml:

- name: Setup Java.
  uses: actions/setup-java@v1
  with:
    java-version: 1.8
    server-list:
      - server-id: value-of-server-id-1
        server-username: SERVER_USERNAME_1
        server-password: SERVER_PASSWORD_1
      - server-id: value-of-server-id-2
        server-username: SERVER_USERNAME_2
        server-password: SERVER_PASSWORD_2

Might produce the following xml in the settings.xml file:

<server>
  <id>value-of-server-id-1</id>
  <username>value-of-server-username-1</username>
  <password>value-of-server-password-1</password>
</server>
<server>
  <id>value-of-server-id-2</id>
  <username>value-of-server-username-2</username>
  <password>value-of-server-password-2</password>
</server>

While it would be valuable in general to be able to specify more than one server, it should be especially valuable in the context of Github, as it seems for now, in order to reference multiple packages from maven.pkg.github.com, the user must reference each package's repository in their pom.xml.

If the above configuration were possible, a user could then reference the artifacts at value-of-server-id-1 and value-of-server-id-2 in their pom.xml as follows:

<dependencies>
  <dependency>
    <groupId>group-id-for-owner</groupId>
    <artifactId>artifact-id-from-repository-1</artifactId>
    <version>version-1</version>
  </dependency>

  <dependency>
    <groupId>group-id-for-owner</groupId>
    <artifactId>artifact-id-from-repository-2</artifactId>
    <version>version-2</version>
  </dependency>
</dependencies>

<repositories>
  <repository>
    <id>value-of-server-id-1</id>
    <name>GitHub Packages</name>
    <url>https://maven.pkg.github.com/owner/artifact-id-from-repository-1</url>
  </repository>
  <repository>
    <id>value-of-server-id-2</id>
    <name>GitHub Packages</name>
    <url>https://maven.pkg.github.com/owner/artifact-id-from-repository-2</url>
  </repository>
</repositories>

what is the current state of this issue?

Same question here. Is this feature on the roadmap? It would be really useful.

[dmitry-shibanov]

Hello everyone. Unfortunately it's not possible to implement right now, because GitHub does not support multiple parameters for arguments. https://github.com/actions/toolkit/issues/184

Surely this could be supported with either a toJSON / fromJSON or by taking a file parameter which contains the relevant content.

Gostaria de saber como funciona

This would be really helpful to have. @IvanZosimov you closed the duplicate https://github.com/actions/setup-java/issues/427, can you provide an update or ping who can push this forward?

I run into the same issue :-( ! Would be really neat to either

1. be able to configure multiple servers,
2. or to access all packages of a given organization via single organization's server: eg: https://maven.pkg.github.com// over https://maven.pkg.github.com//

@roman-bicherschii You can use wildcards to access multiple repos
