Solutions

1. Correct the resource patterns in Settings | Build, Execution, Deployment | Compiler | Resource patterns.
2. Use semicolon-separated wildcard patterns such as ?*.properties;?*.xml without malformed segments.

Example fix

?*.properties;?*.xml;?*.gif;?*.png;?*.jpeg;?*.jpg;?*.html;?*.dtd;?*.tld;?*.ftl

When it happens

Trigger: The compiler resource pattern list contains entries that are not valid wildcard patterns.

Common situations: Hand-entered resource patterns containing illegal characters, empty segments, or malformed wildcards in the Compiler settings.

Understand the failure class

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
