我的目标是从项目中创建一个原型。
当我运行一个不涉及maven-archetype-plugin的目标时,我看不到任何警告:
[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ maven-archetype-base ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 1 resource
[INFO]
[INFO] --- maven-resources-plugin:2.6:testResources (default-testResources) @ maven-archetype-base ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 0 resource
[INFO]
另一方面,当我运行archetype:create-from-project时,我得到了一对:
[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ maven-archetype-base-archetype ---
[WARNING] Using platform encoding (Cp1252 actually) to copy filtered resources, i.e. build is platform dependent!
[INFO] Copying 10 resources
[INFO]
[INFO] --- maven-resources-plugin:2.6:testResources (default-testResources) @ maven-archetype-base-archetype ---
[WARNING] Using platform encoding (Cp1252 actually) to copy filtered resources, i.e. build is platform dependent!
[INFO] Copying 2 resources
我知道“标准”maven方式是使用project.build.sourceEncoding
属性。我尝试在pom中添加一些属性以解决这个问题,但没有一个能够工作。
有什么想法吗?感谢。
我有以下pom.xml:

您尚未设置encoding default属性,如下所示:
<project>
...
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
...
</project>
这种方法比为每个插件手动定义编码要好,导致所有插件都具有encoding for example the maven-resources-plugin的默认值:
encoding:
The character encoding scheme to be applied when filtering resources.
Type: java.lang.String
Required: No
User Property: encoding
Default: ${project.build.sourceEncoding}
因此,这意味着您只需要定义此属性,插件就会自动使用此编码。

当您运行目标archetype:create-from-project
时,Maven会生成一个POM文件,用于在target/generated-sources/archetype/pom.xml
处构建原型,然后在此POM上运行package
目标(默认情况下)。
生成的POM文件没有project.build.sourceEncoding
或任何其他定义编码的属性,这就是您收到警告的原因。
POM是从this prototype org.apache.maven.archetype.creator.FilesetArchetypeCreator#createArchetypeProjectPom
生成的,并且从该代码中看起来似乎不是一种向生成的POM文件添加属性的方法。

我很生气地看到maven在上述条目之后继续抱怨
然后我意识到它是故障安全插件,它需要自己的属性
所以这就是
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties
