java没有规则使目标“external/obpermissionjar/javalib/obpermissionjarPro20160628_1.0.9”为..所需。。？

Question

我想在AOSP中添加第三个库。首先，我把**。外部/obpermission中的jar文件，以及我的Android。mk文件如下：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE:=obpermission
LOCAL_MODULE_TAGES:=optional
LOCAL_MODULE_CLASS:=JAVA_LIBRARIES
LOCAL_MODULE_PATH:=$(TARGET_OUT_JAVA_LIBRARIES)
LOCAL_SRC_FILES:=javalib/obpermissionjar-Pro20160628_1.0.9
include $(BUILD_PREBUILT)

但它在以下方面失败了：

make: *** No rule to make target `external/obpermissionjar/javalib/obpermissionjar-Pro20160628_1.0.9', needed by `out/target/product/generic/obj/JAVA_LIBRARIES/obpermission_intermediates/obpermission'.  Stop.

将其更改为以下内容：

    LOCAL_PATH:= $(call my-dir)
    include $(CLEAR_VARS)
    LOCAL_MODULE:=obpermission
    LOCAL_MODULE_TAGES:=optional
    LOCAL_MODULE_CLASS:=JAVA_LIBRARIES
    LOCAL_MODULE_PATH:=$(TARGET_OUT_JAVA_LIBRARIES)
    LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX)
    LOCAL_SRC_FILES:=javalib/obpermissionjar-Pro20160628_1.0.9.jar
    include $(BUILD_PREBUILT)

您缺少文件路径的尾随.jar。包含LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX)也是一个好主意，但我不认为这是必需的
