Before revision:  We evaluate multi-task learning CoTexT on different generation and classification tasks on CodeXGLUE and it achieves state-of-the-art on all downstream tasks .
After revision:  We evaluate multi-task learning : we perform Code Summarization on 6 different programming languages and Code Refinement on both small and medium size featured in the CodeXGLUE dataset. We further conduct extensive experiments to investigate CoTexT on other tasks within the CodeXGlue dataset, including Code Generation and Defect Detection. We consistently achieve SOTA results in these tasks, demonstrating the versatility of our models .
