Maven 基础

 

 

mvn build 出错:

log：

　　Failed to execute goal on ****** Could not find artifact org.apache.logging.log4j:log4j:jar:2.13.3 in nexus *******, try downloading from https://logging.apache.org/log4j/2.x/download.html -> [Help 1]

原因：

　　此版本只有pom， 需要加tag <type>pom<pom>

 

mvn dependency tree:

　　mvn dependency:tree -Doutput=./dependency_tree/tree.txt

　　mvn dependency:tree > ~/Downloads/tree.txt

 

解压jar/war 包：

 

　　jar -xvf *.war
