我如何以普通用户身份使用 ant 进行构建（不需要 sudo）COOJA
How can I build with ant as a normal user (no need for sudo) COOJA
最近我开始使用 contiki-ng 从事物联网项目。
我遇到的问题是当我尝试 运行 cooja 时：
$ ant run
在 ~/contiki-ng/tools/cooja 之下。
构建失败
$ ant run

我尝试使用 $ sudo ant run ，它开始正常工作，没有问题.

我解决了这个问题，首先检查 build.xml，run 定义的部分：
105. <target name="run" depends="init, compile, jar, copy configs">
106. <java fork="yes" dir="${build}" classname="org.contikios.cooja.Cooja" maxmemory="512m">
107. <sysproperty key="user.language" value="en"/>
108. <arg line="${args}"/>
109. <env key="LD_LIBRARY_PATH" value="."/>
110. <classpath>
111. <pathelement path="${build}"/>
112. <pathelement location="lib/jdom.jar"/>
113. <pathelement location="lib/log4j.jar"/>
114. <pathelement location="lib/syntaxpane-1.2.0.jar"/>
115. <pathelement location="lib/swingx-all-1.6.4.jar"/>
116. </classpath>
117. </java>
118. </target>
您可以看到它取决于 jar。
18. Build COOJA (dist/cooja.jar) and all default projects (MSPSim et al)
19. > ant jar
所以检查 jar 部分：
196. <target name="jar" depends="jar_cooja">
197. <ant antfile="build.xml" dir="apps/mrm" target="jar" inheritAll="false"/>
198. <ant antfile="build.xml" dir="apps/mspsim" target="jar" inheritAll="false"/>
199. <ant antfile="build.xml" dir="apps/avrora" target="jar" inheritAll="false"/>
200. <ant antfile="build.xml" dir="apps/serial_socket" target="jar" inheritAll="false"/>
201. <ant antfile="build.xml" dir="apps/powertracker" target="jar" inheritAll="false"/>
202. </target>
我可以看到它试图操纵 ./apps/serail_socket 但失败了。
所以我检查了这些目录的所有者和正确权限：
$ ls -li | awk '{print , , , $NF}'
total
drwxr-xr-x root root build
-rw-r--r-- user user build.xml
-rw-r--r-- root root cooja.config
drwxr-xr-x root root java
drwxr-xr-x root root lib
-rw-r--r-- root root serial-socket.jar
所有者是 root 而不是普通用户。也许我 运行 :
git submodule update --init --recursive 命令与 sudo 之类的错误。
所以我更改了这些文件和目录的所有者：
sudo chown -h -R user ./apps/serail_socket ./apps/powertracker
然后它的 正常工作。
最近我开始使用 contiki-ng 从事物联网项目。
我遇到的问题是当我尝试 运行 cooja 时：
$ ant run
在 ~/contiki-ng/tools/cooja 之下。
