在指定路径找不到工件 javax.jnlp:jnlp-api:jar:5.0

Could not find artifact javax.jnlp:jnlp-api:jar:5.0 at specified path

我将 slick2d 依赖项添加到我的 pom.xml 文件中,但它在文件顶部突出显示了一个红色错误 Could not find artifact javax.jnlp:jnlp-api:jar:5.0 at specified path,其中显示:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

即使在 运行 vscode 中的测试命令之后,它仍然会给出类似的错误:Could not resolve dependencies for project com.github.shia5347.universalelement:UniversalElement:jar:1.0-SNAPSHOT: Could not find artifact javax.jnlp:jnlp-api:jar:5.0 at specified path /usr/lib/jvm/java-8-openjdk/jre/lib/javaws.jar.

这是我的 pom.xml 以备不时之需:

我正在使用 linux。

解决问题的简单方法是使用 Oracle JDK。

来自位于 https://github.com/nguillaumin/slick2d-maven 的 slick2d 站点:

  • Slick 2D 依赖于 Oracle JDK 附带的 javaws.jar(它在 public Maven 存储库中不可用)。由于这个原因,pom.xml 文件将本地文件系统路径引用到 javaws.jar。
  • 由于上述原因,它不能与 OpenJDK 一起使用(可以通过单独提供 javaws.jar 来解决)。在某些 Linux 发行版上,您可以安装 Netx 并将系统路径更改为指向 netx.jar。例如在 Ubuntu 上要安装的包是 icedtea-netx-common 并且 jar 在 /usr/share/icedtea-web/netx.jar

另请参阅此 link

因为我不喜欢局限于 Oracle JDK,所以我使用以下:

<dependency>
    <groupId>org.slick2d</groupId>
    <artifactId>slick2d-core</artifactId>
    <version>1.0.2</version>
    <exclusions>
        <exclusion>
            <groupId>javax.jnlp</groupId>
            <artifactId>jnlp-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>

这将告诉 maven 跳过 jnlp-api 模块。 它还将允许我将 AdoptOpenJDK 与 slick2d.

一起使用
