>
> 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)
