How do you materialize idempiere? I am using Eclipse Neon 4.6 use Buckminster updated download from Eclipse http://download.eclipse.org/tools/buckminster/updates-4.5 and I am using Java SDK 8 152 version. Also I already clone their repository in https://bitbucket.org/idempiere/idempiere. And I already made Idempiere target platform and I followed the steps in http://wiki.idempiere.org/en/Installation_in_Eclipse but still something error in materializing.
The error in console is this:
ERROR [0015] : No suitable provider for component org.eclipse.jdt.core.compiler.batch:osgi.bundle was found in resourceMap file:/D:/idempiere5.1/org.adempiere.sdk-feature/adempiere.rmap
ERROR [0015] : No suitable provider for component org.eclipse.jdt.core.compiler.batch:osgi.bundle was found in searchPath bundles.maven
ERROR [0015] : Resolution attempt ended with exception: Provider maven2(http://central.maven.org/maven2): Missing CSpec source required by component type osgi.bundle
ERROR Provider maven2(http://central.maven.org/maven2): Missing CSpec source required by component type osgi.bundle
Actually still many more error in console but all the error same. Can't connect the link in http://central.maven.org/maven2.
The page you're looking at is obsolete (I just made a note on that page), please follow the more updated guide at http://wiki.idempiere.org/en/Installing_iDempiere
The two issues I see you're failing: - for 5.1 we need to use Eclipse Oxygen - Buckminster requires installation from a special different URL as described in the guide
