据我所知,cmake从版本2.8.6开始支持java。我找到了命令add_jar,但我似乎无法让它工作。我的CMakeLists.txt看起来像这样:
cmake_minimum_required(VERSION 2.8.10)
find_package(Java)
FILE(GLOB source
"${CMAKE_CURRENT_SOURCE_DIR}/*.java"
)
add_jar(hello ${source})
当我运行cmake时,我得到了这个:
-- The C compiler identification is GNU 4.7.3
-- The CXX compiler identification is GNU 4.7.3
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Found Java: /usr/bin/java (found version "1.7.0.25")
CMake Error at CMakeLists.txt:8 (add_jar):
Unknown CMake command "add_jar".
-- Configuring incomplete, errors occurred!
我在这里缺少什么?
答案 0 :(得分:3)
您还必须包含UseJava
模块。
find_package(Java)
include(UseJava)
add_jar(hello ${source})
find_package
调用仅确定Java安装在磁盘上的位置,而UseJava
模块提供使用Java的函数(如add_jar
)。如文档所述,前者是加载后者的先决条件。
