尝试编译项目时Maven崩溃了＃34;执行Maven时出错。＆＃34;

我正在尝试编译一个使用maven的项目。

运行mvn compile会导致以下错误：

[ERROR] Error executing Maven.
[ERROR] java.lang.IllegalStateException: Unable to load cache item
[ERROR] Caused by: Unable to load cache item
[ERROR] Caused by: Could not initialize class com.google.inject.internal.cglib.core.$ReflectUtils

这种情况发生在我运行它的任何地方，它不必在项目目录中。

我做错了什么？

maven 3.3.9，ubuntu 17.04

mvn -X的完整输出：

2 个答案:

答案 0 :(得分：2)

看起来您正在使用Java 9，请尝试切换到更稳定的Java 8版本。

答案 1 :(得分：2)

看起来maven版本在Java 9上不起作用，但它在Java 8上起作用。

确保您已安装相关软件包，例如...... 

sudo apt install openjdk-8-jre openjdk-8-jdk

然后确保maven使用正确的版本。最简单的方法是将以下行添加到~/.mavenrc的末尾（如果需要，创建它）：

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/

（您可能需要在/usr/lib/jvm/中查找您需要的确切名称，因为它可能与您的系统不同）
