我按照指南执行此步骤：
git clone https://github.com/telefonicaid/fiware-cygnus.git
cd fiware-cygnus/cygnus-common
mvn clean compile exec:exec assembly:single
cp target/cygnus-common-1.1.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext
mvn install:install-file -Dfile=/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.1.0-jar-with-dependencies.jar -DgroupId=com.telefonica.iot -DartifactId=cygnus-common -Dversion=1.1.0 -Dpackaging=jar -DgeneratePom=false
cp target/classes/cygnus-flume-ng /usr/cygnus/bin/cygnus-flume-ng
cd ../cygnus-ngsi
mvn clean compile exec:exec assembly:single
但是在编译cygnus-ngsi的最后一步中我收到了以下错误：

我按照本指南安装了maven，推荐版本在文档（3.2.5）How do I install Maven with Yum?
中Flume已经从cygnus 0.13安装，这是我想升级到1.1.0
我也尝试过这个主题的大部分答案Maven : error in opening zip file when running maven

但doc表示没有任何想法？
我该如何更新0.13版本？我应该卸载cygnus 0.13并在干净的水槽上进行吗？将发布一个yum安装包，就像天鹅座0.13版一样？
答案 0 :(得分：1)
使用3gb ram解决了编译问题，如Packaging cygnus-common results in an empty jar
