在 Ubuntu 上构建 Chromium 期间的失败

Question

我正在尝试按照官方说明构建未修改的 Chromium，但出现以下错误，我尝试重新安装 Ubuntu 8、12 但没有区别：

[10/6591] ACTION Creating jsr_305_javalib jar

Answer 1

我在同样的错误上停止了。最后，我发现了我忘记添加 jar 命令的 PATH 的愚蠢错误。除了 Chromium 官方构建说明中的 java 设置指南之外，还需要以下命令。

sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.6.0_xx/bin/jar 50000

Answer 2

您必须安装 depot_tools 软件包。试试这个命令；

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PATH:/path/to/depot_tools
