----------------------------------------

             Summary: Auto-detected Azul Zulu OpenJDK 8 is not found when 
selecting version 8, 1.8 or 1.8.0
                 Key: MTOOLCHAINS-58
                 URL: https://issues.apache.org/jira/browse/MTOOLCHAINS-58
             Project: Maven Toolchains Plugin
          Issue Type: Bug
    Affects Versions: 3.2.0
            Reporter: Nils Breunese


I have Azul Zulu OpenJDK 8 installed, and it is indeed auto-discovered by 
{{toolchains:display-discovered-jdk-toolchains}}:

{code}
[INFO]   - 
/opt/local/Library/Java/JavaVirtualMachines/openjdk8-zulu/Contents/Home
[INFO]     provides:
[INFO]       version: 1.8.0_432
[INFO]       runtime.name: OpenJDK Runtime Environment
[INFO]       runtime.version: 1.8.0_432-b06
[INFO]       vendor: Azul Systems, Inc.
[INFO]       lts: true
{code}

I then want Maven to use Java 1.8 to build this project by adding this:

{code}
<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-toolchains-plugin</artifactId>
      <version>3.2.0</version>
      <executions>
        <execution>
          <goals>
            <goal>select-jdk-toolchain</goal>
          </goals>
          <configuration>
            <version>1.8</version><!-- I also tried 8 here -->
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>
{code}

But then I get this error message:

{code}
org.apache.maven.plugin.MojoFailureException: Cannot find matching toolchain 
definitions for the following toolchain types:{version=1.8}
Define the required toolchains in your ~/.m2/toolchains.xml file.
{code}

I've also tried setting the version to {{8}} and {{1.8.0}}, but that also 
didn't work.

Setting the version to {{1.8.0_432}} does work, but I don't want to force other 
developers to have this exact Java 8 build installed.
