BUILD FAILED

我尝试通过设置 ANT_OPTS="-Xms256m -Xmx512m"为 Ant 提供更多内存。 (此构建机器具有 1Gb RAM)。

我只是需要更多内存还是可以尝试其他方法？

解决方案似乎是编辑 dx 或 dx.bat shell 脚本(取决于您的平台)并取消注释设置堆大小的行。

例如，

vi $ANDROID_SDK/platforms/*/tools/dx

将允许您在 Mac(也可能是 Linux)上编辑每个 dx 文件。

然后取消注释 javaOpts 行，该行显示如下内容:

# If you want DX to have more memory when executing, uncomment the following
# line and adjust the value accordingly. Use "java -X" for a list of options
# you can pass here.
# 
# javaOpts="-Xmx256M"

这显然不是一个理想的解决方案，因为每次更新平台 SDK 时您的更改都会被破坏。但它确实对我有用。
