maven - 找不到 Artifact Jackson-modules-java8 :jar

Question

我用 打开-jdk-10 .

mvn clean install

在“中央”中找不到 Artifact com.fasterxml.jackson.module:jackson-modules-java8:jar:2.9.8

<?xml version="1.0" encoding="UTF-8"?>

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <maven.compiler.target>10</maven.compiler.target>

            <artifactId>jackson-core</artifactId>
            <version>${jackson.version}</version>
        </dependency>

        <dependency>
            <groupId>com.fasterxml.jackson.module</groupId>
            <artifactId>jackson-modules-java8</artifactId>
            <version>${jackson.version}</version>
        </dependency>
    </dependencies>

</project>

没有 jackson-modules-java8它构建成功。

<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-modules-java8</artifactId>
    <version>${jackson.version}</version>
</dependency>

有一个 similar问题，但它不能解决我的问题。我的 pom 文件中有 maven 依赖项。如果没有其他方法，手动下载东西是我要做的最后一件事。

在 GitHub jackson-datatype-jsr310 您可以阅读的页面:

(DEPRECATED) -- moved under jackson-modules-java8 repo: https://github.com/FasterXML/jackson-modules-java8

在 linked您可以在页面上找到有关 java8 的信息模块:

Note that the parent project -- jackson-modules-java8 -- is ONLY used as parent pom by individual "child" modules, and DOES NOT have dependencies on them.

以及如何使用新模块:

<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-module-parameter-names</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jdk8</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

指向 Maven 存储库的链接:

jackson-datatype-jdk8

All com.fasterxml.jackson.datatype modules
