maven - 为什么 maven 构建在从不正确的 repo 中下载 itext 时失败？

Question

我正在从外部存储库下载某些依赖项。所以我在我的 pom.xml 中添加了以下存储库标签

<repository>
    <id>cdatoolsrelease</id>
    <name>cdatools.com-releases</name>
    <url>http://www.cdatools.com:8081/artifactory/ext-release-local</url>
</repository>
<repository>
    <id>cdatoolssnapshot</id>
    <name>cdatools.com-snapshot</name>
    <url>http://www.cdatools.com:8081/artifactory/libs-snapshot-local</url> 
</repository> 

一切正常。我也可以看到我下载的所需依赖项。但是当我尝试构建这个项目时，我得到以下异常并且构建失败\

我的 pom 文件中没有 itext 依赖项，但我确实有 jasper 依赖项。

<dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>5.1.2</version>
</dependency>

Maven 正在尝试在 cdatools 存储库中搜索 itext 依赖项，但如果它没有得到它，则 maven 构建失败。我怎样才能让它工作。当我删除 repo 时，一切正常，就像在添加新的 repo 标签之前一样

我解决了这个问题，在 pom.xml 中添加了 2 个存储库:

<repository>
    <id>jasper</id>
    <url>http://jasperreports.sourceforge.net/maven2/</url>
    <releases>
    <enabled>true</enabled>
    </releases>
    <snapshots>
    <enabled>false</enabled>
    </snapshots>
</repository>     
<repository>
    <id>jasper1</id>
    <url>http://jaspersoft.artifactoryonline.com/jaspersoft/jaspersoft-repo/</url>
    <releases>
    <enabled>true</enabled>
    </releases>
    <snapshots>
    <enabled>false</enabled>
    </snapshots>
</repository>
