The problem

This check ensures that the number of arguments passed to ‘lenient’ formatting methods like Preconditions.checkArgument match the number of format specifiers.

WARNING: Only the exact two-character placeholder sequence %s is recognized by these methods. Any others will be ignored, and not used for argument substitution.

The APIs checked by this bugpattern include:

• com.google.common.base.Strings#lenientFormat
• com.google.common.base.Preconditions#check*
• com.google.common.base.Verify#verify*
• com.google.common.truth.Truth#assertWithMessage
• com.google.common.truth.Subject#check
• com.google.common.truth.StandardSubjectBuilder#withMessage

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("LenientFormatStringValidation") to the enclosing element.
