Problems importing :libs:elasticsearch-ssl-config project in Eclipse

[cbuescher]

I have encountered this problem since the libs/ssl-config/ project was added a few weeks ago when trying to import this and dependent subprojects.

Things I did to reproduce:

• checkout a clean clone of the elasticsearch repo
• run ./gradlew eclipse (this currently uses Gradle Version 5.1.1)
• "import existing projects" in Eclipse

Symptoms:

• the generated libs/ssl-config/src/main/.classpath file is missing a section defining the code "src" directory and an entry for the dependency on the :libs:core project:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="output" path="build-eclipse"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8/"/>
</classpath>

• as a consequence, the :modules:reindex project is missing classes that should get imported from libs/ssl-config/ (e.g. PemKeyConfig etc..)

Current workaround:

• after manually adding the "java" directory and adding a project dependency to ":lib:core" to the project, the Eclipse workspace looks fine. This changes the libs/ssl-config/src/main/.classpath file to look like the following:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="java"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8/"/>
	<classpathentry combineaccessrules="false" kind="src" path="/:libs:core"/>
	<classpathentry kind="output" path="build-eclipse"/>
</classpath>

My Eclipse Version: 2018-12 (4.10.0)

The workaround currently works for me but it would be nice to get this fixed so people (expecially external contributors) can import the project after just running ./gradlwe eclipse.
