经过一天的努力并阅读了很多关于此的话题，我仍然有问题！我使用Debian 8 jessie并使用以下命令安装maven：
apt-get install maven
这是此命令的结果：mvn -version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.7.0_111, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.16.0-4-amd64", arch: "amd64", family: "unix"
我也用过：git clone https://bitbucket.org/axelclk/info.bliki.wiki.git
获取bliki。然后我去了它的目录并尝试了这个命令：
mvn install -DskipTests
但我得到了这个结果：
root@localhost:/home/m/info.bliki.wiki# mvn install -DskipTests

答案 0 :(得分：2)
您使用的是Java 1.7版
java.util.concurrent.CompletableFuture，java.util.Optional，java.util.OptionalDouble，java.time.ZonedDateTime，etc都是Java 1.8中引入的新功能。它们不存在于Java 1.7中。
要摆脱这些错误，请将Java版本更新为1.8。
