我正在启动一个新的maven项目,该项目将与Spring Boot一起运行(如果相关),并且编译良好。但是后来我决定开始使用Java9模块。所以我让eclipse生成了module-info.java。看起来像这样:
module birdtreemodel {
exports mjl.familytree.birdtree;
requires junit;
requires spring.boot;
requires spring.boot.autoconfigure;
requires spring.boot.test;
requires spring.test;
}
但是,这将导致编译错误。 Eclipse表示“令牌“模块”上的语法错误,预期接口” (并且当我执行Maven全新安装时,它会显示“编译失败:...找不到模块:junit”,对于模块spring.boot.test和spring.test也是如此)
回显%JAVA_HOME%给出C:\ Program Files \ Java \ jdk-12
mvn -version给出:
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:1
4+02:00)
Maven home: D:\Programming practice\maven\apache-maven-3.5.4\bin\..
Java version: 12, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-12
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
该项目的Maven版本的运行配置也位于jdk-12
我的pom看起来像这样:
