Andriy Redko created CXF-8066:
---------------------------------

             Summary: Support Doclet API (JDK13+)
                 Key: CXF-8066
                 URL: https://issues.apache.org/jira/browse/CXF-8066
             Project: CXF
          Issue Type: Improvement
            Reporter: Andriy Redko
            Assignee: Andriy Redko


The com.sun.javadoc.* API is gone in JDK 13 and is replaced with Doclet API. As such, the CXF builds are started to fail on JDK13 for
{noformat}
cxf-java2wadl-plugin{noformat}
 Example:
{noformat}
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project cxf-java2wadl-plugin: Fatal error compiling: CompilerException: NullPointerException -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

[ERROR] For more information about the errors and possible solutions, please read the following articles:

[ERROR] 
[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn <goals> -rf :cxf-java2wadl-plugin{noformat}
(by adding the <forceJavacCompilerUse>true</forceJavacCompilerUse> to maven-compiler-plugin it is possible to get the clear error).

The official migration guide: [https://download.java.net/java/early_access/jdk13/docs/api/jdk.javadoc/jdk/javadoc/doclet/package-summary.html#migration|https://download.java.net/java/early_access/jdk13/docs/api/jdk.javadoc/jdk/javadoc/doclet/package-summary.html#migration).]

We may need to introduce the multi-release JAR since the Java 8/9/10/11 and 13+ implementation are not compatible.
