Question

我在我的项目中使用稀疏矩阵。要构建稀疏矩阵，我正在使用通用Java矩阵包。我将所有依赖项添加到pom.xml文件中。我的pom.xml文件就是这样。

</dependencies>

我自己添加了此依赖项。 ujmp.org网站中的所有依赖项均从该文档中添加。添加所有依赖项后，仍然存在一个错误Error:(30, 16) java: package org.json does not exist.Error:(75, 40) java: cannot find symbol symbol: class JSONTokener location: class org.ujmp.core.util.JsonUtil. Error:(72, 38) java: cannot find symbol symbol: class JSONTokener location: class org.ujmp.core.util.JsonUtil

所以我认为在我的pom.xml文件中添加json依赖关系应该可以消除该错误。

 <dependency>
        <groupId>org.ujmp</groupId>
        <artifactId>ujmp-json</artifactId>
        <version>0.3.0</version>
    </dependency>

但错误未消除，无法识别版本0.3.0。它以红色标志显示。所以我该怎么做？我正在使用Intellij Idea。在UJMP官方网站上没有为json添加依赖项。请给我一个建议。

删除：

<groupId>org.ujmp</groupId>
<artifactId>ujmp-core</artifactId>
<version>0.3.0</version>

添加依赖项：

<dependency>
    <groupId>org.ujmp</groupId>
    <artifactId>ujmp-core</artifactId>
    <version>0.3.0</version>
</dependency>

pom.xml中添加的json依赖获取错误
