A method, system and/or program product corrects semantic errors in code in an integrated development environment. The method includes inputting, using a code editor, code being developed in an integrated development environment. One or more nodes, in a syntax tree constructed for inputting the code, are identified as containing semantic errors pertaining to use of a third-party library. A primary executable code snippet and a secondary code snippet for correcting the semantic errors are displayed. If execution of the primary code snippet does not correct the semantic errors, then the secondary code snippet is automatically executed.
