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.

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