如何只输出分支版本而不真正开始构建

Question

当运行:

green@green13:~/green/build$bitbake core-image-minimal

我可以看到如下的分支版本，它会开始构建，但我只需要这些信息输出，并不真的需要开始构建，我该怎么做？


Build Configuration:
BB_VERSION           = "1.46.0"
BUILD_SYS            = "x86_64-linux"
NATIVELSBSTRING      = "universal"
TARGET_SYS           = "aarch64-poky-linux"
MACHINE              = "qemuarm64"
DISTRO               = "poky"
DISTRO_VERSION       = "3.1.14"
TUNE_FEATURES        = "aarch64 armv8a crc"
TARGET_FPU           = ""
meta                 
meta-poky            
meta-yocto-bsp       = "HEAD:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
meta-oe              
meta-python          
meta-filesystems     
meta-networking      = "HEAD:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
meta-virtualization  = "HEAD:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

你可以这样做：

bitbake core-image-minimal -n

-n arguments 执行干运行，从技术上讲，它会启动构建，但不会做太多事情，它会在几秒钟内完成。

例如：

$ bitbake core-image-minimal -n

TARGET_SYS           = "aarch64-poky-linux-musl"
MACHINE              = "qemuarm64"
DISTRO               = "poky-tiny"
