我目前有 3.0.5 版本的 maven，当我运行
mvn -version
我明白了
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option

因此，我可以让 Maven 获取特定版本的前端插件（我最终可能会这样做），或者我可以更新 Maven。因此，我决定更新 Maven，然后运行以下命令
sudo apt-get --only-upgrade install maven
作为回应，我得到了
Reading package lists... Done
Building dependency tree
Reading state information... Done
maven is already the newest version.
解决这个问题的最佳方法是什么？我正在考虑卸载 Maven，但我希望在这里得到快速回复。谢谢！

我遵循了这里的建议如何更新 maven 3.0.4 - 3.1.1这基本上
cd ~/Downloads
wget http://apache.mirrors.tds.net/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.tar.gz
sudo mkdir -p /usr/local/apache-maven
sudo mv apache-maven-3.1.1-bin.tar.gz /usr/local/apache-maven
cd /usr/local/apache-maven
sudo tar -xzvf apache-maven-3.1.1-bin.tar.gz
Edit ~/.profile with gedit ~/.profile and add these four lines:
export M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
export M2=$M2_HOME/bin
export MAVEN_OPTS="-Xms256m -Xmx512m"
export PATH=$M2:$PATH
