> While working on CASSANDRA-20328 I had to make a small tweak to allow sstableloader to work in eclipse with its source moved to a new tools-specific directory.
> While doing this I noticed that eclipse project generation was not functional for the following reasons:
>  # A classpath entry is added for {{${java.home}/../lib/tools.jar}}, which no longer exists after JDK 9 ([JEP-220|https://openjdk.org/jeps/220])
>  # The generated .classpath file appears to be invalid xml due to some injection of backslashes when closing off an element. This appears to have been added in CASSANDRA-17294; It's possible that this worked at some point and was broken for some other reason.
>  # Build fails because modules are not exported (e.g. missing {{--add-exports}}, {{-add-opens}}, which is needed for JDK11+.
>  # Some dependencies, such as {{high-scale-lib}} includes package names that exist in the core jdk (such as {{java.util}} and {{java.util.concurrent}}) which causes ecj to complain and fail to build, this is fixable by adding {{org.eclipse.jdt.core.compiler.ignoreUnnamedModuleForSplitPackage=enabled}} to {{.settings/org.eclipse.jdt.core.prefs}}.
>  # Classpath does not specify a minimum JDK requirement so an older JDK may be chosen which would fail the build (Not strictly necessary, but nice to remove any ambiguity about Java runtime selection)
