Precondition Violations (3)
Row |
Violation |
1 | Type java.lang.String of variable var does not match with type org.apache.tools.ant.util.FileNameMapper of variable mapper |
2 | Unmatched throw new BuildException(ERROR_TOO_MANY_MAPPERS); |
3 | Unmatched statement var=line; cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted |
