Is GNU General Public License v2.0 compatible with Eclipse Public License 2.0?

No

GNU General Public License v2.0 is strong copyleft; combining it into a Eclipse Public License 2.0 project would force the combined work to be GNU General Public License v2.0 (not Eclipse Public License 2.0). If your project must remain Eclipse Public License 2.0, avoid GNU General Public License v2.0 code.

If you found this page because you're trying to figure out whether shipping a particular dependency is safe, the answer above is a starting point — not a substitute for reading the actual licenses or talking to a lawyer when stakes are high.

LicenseHound walks every transitive dependency in your repo, maps each to its SPDX license, and flags pairs like this one in PR comments. The CLI is free; the team dashboard is paid.
