I found the infer will capture the ant project's build log and use infer to javac build the java file again. But when some java file's dependences are deleted along with building procession and can not find the jar and java files, the infer-javac would failed.

Research direction
Focus on the Ant integration in Infer's source code, likely in the capture step. The issue is that during re building with infer javac, dependencies are missing. Examine how Infer captures the build log and sets up the classpath. Look for code that extracts Java source files and their dependencies from the Ant build. Propose a fix to preserve the full classpath or to re extract dependencies before each javac invocation.
