我是Maven的新手,我遇到了以下问题:我已经创建了一个示例Maven项目,并且我试图制造一些战争。我已经在我的pom.xml中添加了几个依赖项,但我无法弄清楚如何将JRE添加到classpath中。当我编译war模块时,我收到以下错误:
[ERROR] /C:/path/to/class/PreferredMapper.java:[3,44] package com.sun.xml.internal.bind.marshaller does not exist
[ERROR] /C:/path/to/class/PreferredMapper.java:[11,38] cannot find symbol
symbol: class NamespacePrefixMapper
类NamespaceprefixMapper
包含在JRE的库rt.jar
中,因此我猜测我的JRE不在编译类路径中。我已经尝试在我的pom.xml中添加JRE作为依赖项,但它无法正常工作。
将JRE库添加到类路径的正确方法是什么?
EDIT1:
战争模块pom.xml:

这是一个带有ear and war模块的多模块项目。我试图通过运行mvn install
命令将工件安装到我的本地存储库。
答案 0 :(得分:0)
我会添加一个属性部分,其中包括以下内容(根据需要更改版本)
<properties>
<java.version>1.8</java.version>
</properties>
然后添加编译器插件
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
我认为我已经看到了更优雅的做法,但这就是我以前所做的。
