指定依赖项POM XML的字符编码

Question

问题

运行时gradle jar,我收到以下错误消息.

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all files for configuration ':compileClasspath'.
> Could not resolve javax.units:jsr108:0.01.
  Required by:

         > Invalid byte 2 of 3-byte UTF-8 sequence.

我用Gradle 4.1(目前最新的)和Gradle 3.2.1测试了这个,它给出了同样的错误.

实际上,查看错误URL中的POM文件,可以看出该文件的编码是Windows-1252,而不是UTF-8.为什么会出现错误是明确的,但我怎么能解决这个问题？我无法控制POM文件的字符编码.如何告诉Gradle非UTF-8编码？

再现这个问题

这是一个重现错误的最小项目.

build.gradle

apply plugin: 'java'

repositories {
    maven {
        url 'http://download.osgeo.org/webdav/geotools'
    }
}

dependencies {
    // https://mvnrepository.com/artifact/org.geotools/gt2-metadata
    compile group: 'org.geotools', name: 'gt2-metadata', version: '2.5-M1'                                                                                                                                        
}

src/main/java/HelloWorld.java

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

另一种可能性是手动下载 JAR 并将项目配置为使用该引用运行。该错误似乎是下载过程的一部分，如果您绕过该过程，源代码将编译并运行。

mvnrepository.com上有一个下载链接。

您可以将 JAR 安装到 Maven 本地存储库中

/home/you/.m2/repository/org/geotools/gt2-metadata/2.5-M1/gt2-metadata-2.5-M1.jar

您可以通过没有依赖项、运行gradle jar并查看错误消息来找到该路径。在下面的第二行中，以 开头的file:是您要安装 JAR 的路径。

这是我的build.gradle文件：

apply plugin: 'java'

apply plugin: 'application'

mainClassName = 'hello.HelloWorld'

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    // https://mvnrepository.com/artifact/org.geotools/gt2-metadata
    compile group: 'org.geotools', name: 'gt2-metadata', version: '2.5-M1'
