Question

我的新项目需要javax.xml软件包。我确实在mvnrepository.com中进行了搜索，发现one：

<!-- https://mvnrepository.com/artifact/javax.xml/jaxrpc-api -->
<dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxrpc-api</artifactId>
    <version>2.0_EA1</version>
</dependency>

我想，第一个注释行是软件包存储库。请，如果我错了，请纠正我。我在pom.xml中添加了以下部分：

<repositories>
  <repository>
    <id>repo1</id>
    <name>Repo 1</name>
    <url>https://mvnrepository.com/artifact/javax.xml/jaxrpc-api</url>
  </repository>
</repositories>

<dependencies>
  <dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxrpc-api</artifactId>
    <version>2.0_EA1</version>
  </dependency>
</dependencies>

但是看起来我输入了错误的Maven地址。

mvn compile带来了错误：

[ERROR] Failed to execute goal on project test-xpath: Could not resolve dependencies for project com.kkk:test-xpath:jar:0.0.1-SNAPSHOT: Failure to find javax.xml:jaxrpc-api:jar:2.0_EA1 in https://mvnrepository.com/artifact/javax.xml/jaxrpc-api was cached in the local repository, resolution will not be reattempted until the update interval of repo1 has elapsed or updates are forced -> [Help 1]

我做错了什么以及如何解决？

UPD

删除存储库后出现错误：

 Failed to execute goal on project test-xpath: Could not resolve dependencies for project com.kkk:test-xpath:jar:0.0.1-SNAPSHOT: Failure to find javax.xml:jaxrpc-api:jar:2.0_EA1 in https://mvnrepository.com/artifact/javax.xml/jaxrpc-api was cached in the local repository, resolution will not be reattempted until the update interval of repo1 has elapsed or updates are forced -> [Help 1]

UPD2

我了解到应该将spring存储库添加到我的依赖项中：

    <repositories>
    <repository>
      <id>repo1</id>
      <name>Repo 1</name>
      <url>http://repo.spring.io/plugins-release/</url>
    </repository>
  </repositories>

我已删除.m2\repository\javax，并做了maven clean

maven compile产生错误：

如果我在pom.xml中没有<repository>的情况下执行了相同的操作，并且执行了maven compile，则我有相同的错误，但是它尝试从maven.repo下载pom。

Answer 1

这不是正确使用存储库标记的方法。如果转到https://mvnrepository.com主页，您会看到它从多个存储库（例如中央存储库，jcenter存储库等）建立索引。因此，您必须使用标准存储库。

Answer 2

如果打开maven repository页面，我们可以看到两个标签：中央插件和Spring插件。打开Spring插件标签，并尝试使用它，因为该版本是最新的，并且日期为2018年4月。

<!-- https://mvnrepository.com/artifact/javax.xml/jaxrpc-api -->
<dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxrpc-api</artifactId>
    <version>2.0_ea1</version>
</dependency>

另外，运行mvn clean命令，并确保删除javax位置的.m2文件夹。

Answer 3

2.0_EA1在Maven Central上不存在。如果您使用1.1，您将看到它有效。非规范化semver版本似乎与非官方版本有关，可能是alpha版本。在search.maven.org上的搜索声称它存在，但jar本身不存在

要检查工作版本，请执行以下操作：

<dependencies>
  <dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxrpc-api</artifactId>
    <version>1.1</version>
  </dependency>
</dependencies>

还请注意：错误Maven显示会告诉您，您可以从URL（不是存储库）中手动下载jar。

要仅回答问题的标题，您可以将存储库添加到pom.xml中，但是不需要添加中央Maven存储库，因此，我为您提供另一个存储库的示例：

<repositories>
    <repository>
        <id>jitpack</id>
        <name>jitpack</name>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

设置Maven存储库
