VScode编译报错：正在执行任务: CMake: build build failed. * 终端进程启动失败(退出代码: -1)。 * 终端将被任务重用，按任意键关闭。

主要原因是：没有 source 工作空间的 devel/setup.bash

task.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "shell",
			"label": "Catkin: build",
			"command": "bash",
			"args": [
				"-lc",
				"cd \"${workspaceFolder}\" && if [ -f devel/setup.bash ]; then source devel/setup.bash; fi && catkin_make"
			],
			"options": {
			"cwd": "${workspaceFolder}"
			},
			"presentation": {
				"reveal": "always",
				"panel": "shared"
			},
			"group": {"kind":"build", "isDefault": true},
			"problemMatcher": ["$gcc"],
			"detail": "Catkin_make template build task"
		}
	]
}

bash -lc "..." 可保证在一段干净的 shell 环境中先 source ROS，再执行 catkin_make，可避免 catkin_make: command not found。
