To Sir Michael:
Thank you for your guiding, my steps are:
cd /data/workspace/OxyCentos/HadoopCas/cassandra-trunk
git clone https://github.com/apache/cassandra.git
cd cassandra-trunk/
git checkout -b cassandra-3.11.3
ant artifacts
The steps all build successfully, and the returnings info from "ant artifacts"
is:
BUILD SUCCESSFUL
Total time: 5 minutes 58 seconds
[gloCalHelp.com@gloCalHelp1 cassandra-trunk]$ git status
# On branch cassandra-3.11.3

Merge branch 'cassandra-3.0' into HEAD
The "ant generate-eclipse-files" 's returnings are:
[copy] Warning: functions modified in the future.
[copy] Warning: tokenization modified in the future.
generate-eclipse-files:
[mkdir] Created dir:
/data/workspace/OxyCentos/HadoopCas/cassandra-trunk/.settings
BUILD SUCCESSFUL
Total time: 12 seconds
then I follow the page you offer's steps are:
Start Eclipse.
Select File->Import->Existing Projects into Workspace->Select git directory.
Make sure “cassandra-trunk” is recognized and selected as a project
and then from menu Project-> clean -> build only the selected projects..
but there are still the same only 3 errors left on the 1 line code:
1, The method map(Function<? super Cell,? extends R>) in the type Stream<Cell>
is not applicable for the arguments (((transform != null) ? transform : (<no
type> cell) -> "")) AbstractRow.java
/cassandra-trunk/src/java/org/apache/cassandra/db/rows line 183 Java
Problem
2, Type mismatch: cannot convert from Function<Cell,String> to Function<? super
Cell,? extends R> AbstractRow.java
/cassandra-trunk/src/java/org/apache/cassandra/db/rows line 183 Java
Problem
3, Type mismatch: cannot convert from String to R AbstractRow.java
/cassandra-trunk/src/java/org/apache/cassandra/db/rows line 183 Java
Problem
how to solve the cassandra 3.11.3 source's compiling errors exactly?
Thank you!
Sincerely

other big data system?
You have a dirty build environment. Your path of "/cassandra-trunk/src"
in the error and the suggestion on slack that you are trying to build
cassandra-3.11.3 shows me you need to start over fresh. Here you go:
build docs:
http://cassandra.apache.org/doc/latest/development/ide.html
build steps pasted in slack:#cassandra:
cd /tmp/
git clone https://github.com/apache/cassandra.git
cd cassandra/
git checkout cassandra-3.11.3
ant artifacts
BUILD SUCCESSFUL
