Question

我在＆＃34; mvn clean install＆＃34;上收到错误消息命令，如下：

    Failed to execute goal on project image-server-core: 
    Could not resolve dependencies for project com.xxxx:image-server-core:jar:2.0.7: 
Failure to find javax.transaction:jta:jar:1.0.1B in
    http://repo1.maven.org/maven2 was cached in the local repository, resolution
    will not be reattempted until the update interval of repo1.maven.org has elapsed or updates are forced ->

我做了一些谷歌搜索，并尝试添加以下依赖

<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>

但它只是说禁止访问。虽然这似乎是一个相当常见的错误，但我对maven的理解非常有限 - 例如，如何跟踪链接到javax.transaction的依赖关系：jta：jar：1.0.1B？更重要的是，我该如何解决这个问题？

这是pom.xml：

Answer 1

根据你的pom.xml，我发现了hibernate maven依赖，但是你的hibernate版本是什么？如果你像下面那样更新hibernate：

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate</artifactId>
 <version>3.3.2.ga</version>
</dependency>

它有一个推荐的jta依赖项。所以更新你的hibernate版本。更多细节：maven missing dependency jta-1.0.1b

还有，你的pom.xml都有log4j和logback maven依赖。请看一下log4j和logback：log4j vs logback之间的区别，如果你想使用logback而不是log4j，你会删除log4j maven依赖，还要添加slf4j maven依赖：

 <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.25</version>
    </dependency>

Answer 2

由于maven存储库中不存在此依赖项，因此可以将其直接添加到本地存储库中。首先从Oracle网站https://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-database-419422.html

下载jar。

文件名将为 jdbc2_stdext.jar 或类似名称。

现在您可以使用以下命令将其安装在本地Maven中：

mvn install:install-file -DgroupId=javax.sql -DartifactId=jdbc-stdext -Dversion=2.0 -Dpackaging=jar -Dfile=jdbc-stdext.jar

如何解决＆＃34;未能找到javax.transaction：jta：jar：1.0.1B＆＃34;在maven安装？
