Is there a way to make maven build class files with UTF-8 without using the external JAVA_TOOL_OPTIONS?
提问by chrisapotek
I don't want to be dependable on a external environment variable to force maven to build my classes with UTF-8. On Mac, I was getting all sorts of problems when building with maven. Only the option below solved the problem:
我不想依赖外部环境变量来强制 maven 使用 UTF-8 构建我的类。在 Mac 上，我在使用 maven 构建时遇到了各种各样的问题。只有以下选项解决了问题：
export JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8
mvn clean install
However I am distributing my project and it does NOT make sense to rely on the user to set this environment variable to build the project correctly.
但是，我正在分发我的项目，依靠用户设置此环境变量来正确构建项目是没有意义的。
Tried everything as described here: enabling UTF-8 encoding for clojure source files
按照此处所述尝试了所有内容：为 clojure 源文件启用 UTF-8 编码
Anyone has a light on that awesome Maven issue?
任何人都对那个很棒的 Maven 问题有所了解？

It is not enough to define that property. You MUST pass it inside the appropriate plugins. It won't go by magic inside there.
仅定义该属性是不够的。您必须在适当的插件中传递它。它不会在里面变魔术。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>...</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
<encoding>${project.build.sourceEncoding}</encoding>

Yes there is, define
是的，定义
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

I was running into this problem, but only when running the compile from Emacs. I could not change the project's poms. What worked for me was to put the following in ~/.mavenrc
我遇到了这个问题，但仅限于从 Emacs 运行编译时。我无法更改项目的 poms。对我有用的是将以下内容放入 ~/.mavenrc
LANG=en_US.UTF-8
