不正確的Java版本試圖構建android源碼

Question

我想構建android源碼，並得到一個奇怪的錯誤。我選擇使用

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

和

$ update-alternatives --config java 
$ update-alternatives --config javac 

的java當我運行make -j4我得到

Your version is: java version "1.7.0_72". 
The correct version is: Java SE 1.6. 

當我運行sudo make -j4我得到

Your version is: java version "1.6.0_33". 
The correct version is: Java SE 1.6.

Answer 1

我爲我所有的AOSP和Cyanogenmod建築使用openjdk-6-jdk，而且我從來沒有錯誤。我不確定爲什麼谷歌會一直要求Oracle的東西，但恕我直言，它不是純粹的技術。所以我的建議是在makefile build/core/main.mk中註釋錯誤代碼（請看'＃'註釋）：

ifeq ($(strip $(java_version)),) 
$(info ************************************************************) 
$(info You are attempting to build with the incorrect version) 
$(info of java.) 
$(info $(space)) 
$(info Your version is: $(java_version_str).) 
$(info The required version is: $(required_version)) 
$(info $(space)) 
$(info Please follow the machine setup instructions at) 
$(info $(space)$(space)$(space)$(space)https://source.android.com/source/initializing.html)
