The problem is in core folder's gradle file. Can you show me that file?
The content of core's directory gradle file should be :
apply plugin: 'java-library-distribution'
jar {
baseName = 'hipi'
version = '2.1.0'
}
distributions {
main{
baseName = 'hipi'
version = '2.1.0'
}
}
javadoc {
title = "HIPI - Hadoop Image Processing Interface"
options.links("http://docs.oracle.com/javase/8/docs/api/",
"http://hadoop.apache.org/docs/stable/api/",
"http://javadoc.metadata-extractor.googlecode.com/git/2.7.0/",
"http://bytedeco.org/javacpp-presets/opencv/apidocs/")
}
test {
testLogging.showStandardStreams = true
}
