As per your highligted error message, I suggest configure not to compress the jar.

The jar and war plugins have an entryCompression property. If set to ZipEntryCompression.STORED the entries of the archive are left uncompressed.

Example:

jar {
     entryCompression = ZipEntryCompression.STORED
}

From Gradle API Documentation

The compression level of the entries of the archive. If set to ZipEntryCompression.DEFLATED (the default), each entry is compressed using the DEFLATE algorithm. If set to ZipEntryCompression.STORED the entries of the archive are left uncompressed.
