We don't reference platform products in our build but use the target-platform-validation-plugin [1], whose validate-target-platform goal apparently also stumbles over the missing entries: > [INFO] --- target-platform-validation-plugin:1.0.0:validate-target-platform (validate-target-platform) @ photon --- > [INFO] Validating /Users/sewe/Documents/oomph/org.eclipse.recommenders/git/org.eclipse.recommenders/targets/photon/photon.target... > [INFO] Fetching p2.index from http://download.eclipse.org/eclipse/updates/4.8milestones/S-4.8M5-201801242000/ > [INFO] Adding repository http://download.eclipse.org/eclipse/updates/4.8milestones/S-4.8M5-201801242000 > [INFO] Adding repository http://download.eclipse.org/modeling/emf/emf/updates/2.14milestones > [INFO] Fetching p2.index from http://download.eclipse.org/tools/orbit/downloads/drops/S20180119201206/repository/ > [INFO] Fetching p2.index from http://download.eclipse.org/tools/orbit/downloads/drops/S20180119201206/repository/ > [INFO] Adding repository http://download.eclipse.org/tools/orbit/downloads/drops/S20180119201206/repository > [INFO] Fetching p2.index from http://download.eclipse.org/tools/orbit/downloads/drops2/S20180119201206/repository/ > [INFO] Fetching p2.index from http://download.eclipse.org/tools/orbit/downloads/drops2/S20180119201206/repository/ > [ERROR] Cannot resolve target definition: > [ERROR] Problems resolving provisioning plan.: > [ERROR] Unable to satisfy dependency from org.eclipse.sdk.ide 4.8.0.I20180124-2000 to config.a.jre.javase [9.0.0]. > [ERROR] Unable to satisfy dependency from org.eclipse.sdk.ide 4.8.0.I20180124-2000 to a.jre.javase [9.0.0]. > [ERROR] > [INFO] Failed, see Error log below > [ERROR] Validation found errors in 1 .target files: > Could not resolve content of photon.target Alas, I couldn't get the workaround to work: > So if you see this error, it requires some action: > * you can use a workaround to explicitly add the (config.)a.jre.javase > [9.0.0] units in your target platform.
