Examples with RemoteConnectionException org.eclipse.remote.core.exception.RemoteConnectionException used on opensource projects

Example 1 with RemoteConnectionException

use of org.eclipse.remote.core.exception.RemoteConnectionException in project linuxtools by eclipse.

the class RDTProxyManager method getEnv.

    IRemoteConnection connection = getConnection(uri);

         * It is common to export functions declaration in the environment so
         * this pattern filters out them because they get truncated and might
         * end up on failure. When a function is exported it makes a mess in ENV
         * and none of LT plugins working remotely because they are not find on
         * path.
         *
         * Patterns added in the env list:
         * var=value
         * i.e: SHELL=/bin/bash
         *
         * Patterns not added in the env list:
         * var=() { foo
         * i.e: BASH_FUNC_module()=() { eval `/usr/bin/modulecmd bash $*`, }
