构建OpenJDK - 缺少antlr3

Question

我正在尝试构建OpenJDK但是从gradle那里得到一个错误：

FAILURE: Build failed with an exception.

* Where:
Build file '/home/pi/openjdk/rt/buildSrc/build.gradle' line: 86

* What went wrong:
A problem occurred evaluating root project 'buildSrc'.
Cause: Could not find method antlr3() for arguments [{group=org.antlr, 
name=antlr-runtime, version=3.1.3}] on root project 'buildSrc'.

我安装了antlr3并在我的classpath中。命令

java org.antlr.Tool -version

返回

ANTLR Parser Generator  Version 3.5.2

我错过了什么？
