Fault Tolerance 2.1: org.eclipse.microprofile.faulttolerance cannot be resolved

[Azquelt]

Describe the bug

The bug seems to be caused by the Fault Tolerance 2.1 API feature not having a dependency on the Fault Tolerance 2.1 API jar

• https://mvnrepository.com/artifact/io.openliberty.features/com.ibm.websphere.appserver.org.eclipse.microprofile.faulttolerance-2.1/20.0.0.6

The corresponding 2.0 API feature does have this dependency (as do all the other openliberty feature in maven central I looked at)

• https://mvnrepository.com/artifact/io.openliberty.features/com.ibm.websphere.appserver.org.eclipse.microprofile.faulttolerance-2.0/20.0.0.6

Steps to Reproduce

1. Add the following in the server.xml:

<feature>mpFaultTolerance-2.1</feature>

(or <feature>microProfile-3.3</feature>)

2. Add the following in the pom.xml:

<dependency>
    <groupId>io.openliberty.features</groupId>
    <artifactId>mpFaultTolerance-2.1</artifactId>
    <type>esa</type>
    <scope>provided</scope>
</dependency>

(or <artifactId>microProfile-3.3</artifactId>)

3. import a FT feature, i.e.

import org.eclipse.microprofile.faulttolerance.Retry;

The microprofile-fault-tolerance-api-2.1.1.jar does not built, and hence the following error message will appear: The import org.eclipse.microprofile.faulttolerance cannot be resolved

Expected behavior
Adding <feature>mpFaultTolerance-2.1</feature> should import the dependency, and the FT features should be resolved

Diagnostic information:

• OpenLiberty Version:

• server.xml configuration:

  <featureManager>
    <feature>jpa-2.2</feature>
    <feature>jdbc-4.2</feature>
    <feature>jndi-1.0</feature>
	<feature>microProfile-3.3</feature>
  </featureManager>

Additional context
The error seems to be caused by the feature not being correctly linked to the fault tolerance api in maven central.

Adding the following dependency resolves the issue:

<dependency>
    <groupId>org.eclipse.microprofile.fault-tolerance</groupId>
    <artifactId>microprofile-fault-tolerance-api</artifactId>
    <version>2.1.1</version>
    <scope>provided</scope>
</dependency>
