Question

这是Android源代码编译。

在几个晚上重复“repo sync”之后，然后“make -j4”我将在编译的每个不同日期得到以下错误。（我的Java是Oracle JDK的6u45版本，主机是Linux Ubuntu 64位LTS 14.04）。但是做同样的事情（从“repo sync”编译）不会导致另一个Ubuntu 14.04 LTS（64位）出错，我甚至可以执行“模拟器”来启动另一台机器上的asop_arm-eng模拟器映像。第一台机器肯定有问题。

谷歌搜索没有发现任何类似的错误，有人请帮忙吗？

我已经确认了我的javap，但注意到此错误的更改。我的环境是（ubuntu15.04，python2.7.6，java1.6.0_45，gcc4.8.2）所以我改变了“external / chromium_org / base / android / jni_generator / jni_generator.py”，删除了错误。

diif如下:(“def MultipleReplace”的缩进与“class InlHeaderFileGenerator”相同）

我也有同样的问题在对上述回答问题中的一些想法进行了跟进之后，我就解决了这个问题：

sudo apt-get remove openjdk-6-jdk  
sudo apt-get remove openjdk-8-jdk  
sudo apt-get autoremove

足以简单地使用以下命令选择oracle版本：

sudo update-alternatives --config java  
sudo update-alternatives --config javac

我必须真正去除这些包裹目前尚不清楚我是否只需删除其中一个，我删除了两个！
