another question
when I run the code org.apache.druid.segment.SegmentUtilsTest#testVersionBin from the source 0.22.1(git clone from github)
public void testVersionBin() throws Exception
{
File dir = tempFolder.newFolder();
FileUtils.writeByteArrayToFile(new File(dir, "version.bin"), Ints.toByteArray(9));
Assert.assertEquals(9, SegmentUtils.getVersionFromDir(dir));
}
error occur:
E:\source\druid-druid-0.22.1\core\src\main\java\org\apache\druid\math\expr\ExprListenerImpl.java:29:40
java: package org.apache.druid.math.expr.antlr does not exist
i do not edit any code ,why the package antlr missing?
