我从 Maven Alfresco 原型(prototype)生成了一个项目:
mvn archetype:generate -Dfilter=org.alfresco:
当我尝试构建时失败:

D:\Mehrdad\alfresco>java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
D:\Mehrdad\alfresco>javac -version
javac 1.8.0_231
如您所见，java 和 javac 是 8。我不知道如何解决这个问题。
有什么问题吗？
最佳答案
它提示某些类文件是使用 Java 11(即 Java 55.0， List of Java class file format major version numbers? )编译的，而您尝试使用 Java 8 编译其余部分。
您应该将本地 Java 版本更新到至少 Java 11，然后尝试再次重新编译
关于java - 构建 Alfresco 时出现错误 "class file has wrong version 55.0, should be 52.0"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60612488/
