を受け入れるメソッドを呼び出していますInputStream。github のメソッドは次のとおりです: https://github.com/drewnoakes/metadata-extractor/blob/2.8.0/Source/com/drew/imaging/ImageMetadataReader.java#L89
BufferedInputStreamの子であるため、動作するはずのメソッドを呼び出していInputStreamますが、このエラーが発生し続けます:
No signature of method: static com.drew.imaging.ImageMetadataReader.readMetadata() is applicable for argument types: (java.io.BufferedInputStream) values: [java.io.BufferedInputStream@74d4ec5f]
Possible solutions: readMetadata(java.io.File), readMetadata(java.io.BufferedInputStream, boolean). Stacktrace follows:

これが私のコードです：
println file62.name //prints name of the file
println file62.inputStream.getClass() //prints java.io.BufferedInputStream
InputStream is = (InputStream)file62.inputStream
Metadata metadata = com.drew.imaging.ImageMetadataReader.readMetadata(is) //readMetadata expects InputStream
私が持っているライブラリのバージョン:
✗ grails dependency-report | grep "drew"
+--- com.drewnoakes:metadata-extractor:2.9.1
+--- com.drewnoakes:metadata-extractor:2.9.1
+--- com.drewnoakes:metadata-extractor:2.9.1
これは 2.9.1 のメソッドです: https://github.com/drewnoakes/metadata-extractor/blob/2.9.1/Source/com/drew/imaging/ImageMetadataReader.java#L88
