java - 如何引导构建 jdk？

问题描述

我正在尝试构建jdk-11+8以读取生成的java.nio.ByteBufferLinux 源代码。

我根据文档安装了所有依赖项，然后成功运行configure。

但是，当我运行时make，我收到一个关于缺少 Java 包的奇怪错误，这看起来像是一个引导问题。

git clone https://github.com/openjdk/jdk.git 
pushd jdk
bash configure
...
The existing configuration has been successfully updated in
/home/ubuntu/Code/jdk/build/linux-x86_64-normal-server-release
using default settings.

make clean

我错过了什么？

更多系统细节：

ubuntu@box:~$ uname -a
Linux box 4.15.0-1057-aws #59-Ubuntu SMP Wed Dec 4 10:02:00 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
ubuntu@box:~$ cat /etc/issue
Ubuntu 18.04.4 LTS \n \l

再挖掘一点，我还看到以下错误，可能相关也可能不相关：

解决方案

事实证明，我使用 JDK 11 作为引导 JDK，这不起作用，因为该javax.annotations软件包已从JDK 11 中删除。

手动降级到 jdk 10 并指向configure它为我解决了这个问题。

wget https://download.java.net/java/GA/jdk10/10.0.2/19aef61b38124481863b1413dce1855f/13/openjdk-10.0.2_linux-x64_bin.tar.gz
tar xf openjdk-10.0.2_linux-x64_bin.tar.gz

bash configure --with-boot-jdk=/home/ubuntu/Code/jdk10/jdk-10.0.2
make

由于jdk 10已弃用，我不得不从存档中提取链接。
