Question

我有第三方JAR，我通过pom.xml命令创建了一个工件。工件被添加到项目中，模块的<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <packaging>pom</packaging> <name>Sandbox</name> <parent> <groupId>com.x.y</groupId> <artifactId>third-party-parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>com.x.y.z</groupId> <artifactId>thirdparty-z</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>com.x.y.thirdparty</groupId> <artifactId>thirdparty-sources</artifactId> <version>1.0</version> </dependency> <dependency> <groupId>com.x.y.thirdparty</groupId> <artifactId>thirdparty-compiled</artifactId> <version>1.0</version> </dependency> </dependencies> </project>和导入就好了。

使用第三方JAR中的符号创建Java类仍然无法解决。红灯灯泡显示，并且没有像我期望的那样选择“导入类”。

我试图使缓存失效|重启但无济于事。

有什么想法吗？

编辑如果我改为安装已编译的JAR，则解析符号。为什么会这样？

编辑2 添加显示内部共享工件的pom.xml。

.sf-menu li:first-child a, .sf-menu li:first-child a:hover {
    padding: 0;
}   
 li.menu-item a {
        padding-top: 20px;
    }

此Maven项目文件pom.xml包含修复程序，以及有关更改内容及其更改原因的一些提示/提示。

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

    <modelVersion>4.0.0</modelVersion>

    <!--  Parent POM best at the top  -->
    <!--  WANRING: Here you import the parent of 3th party. This is (almost) never correct!!!  -->
    <!--  For a simple project, which only exists of 1 set of classes and unit tests, you do   -->
    <!--  not need a parent POM. Only for multi module Maven project, you will have a parent   -->
    <!--  POM. Or for organisation wide configuration, of repositories, Maven plugin           -->
    <!--  configuration, and so. When starting with a small project, leave out the parent POM  -->
    <!--  reference.                                                                           -->

    <artifactId>your-project-name</artifactId>
    <packaging>pom</packaging>
    <name>My Little Sandbox</name>
    <version>1.0.0-SNAPSHOT</version>

    <dependencies>
        <!--  Here only a reference to the compiled jar is required!!!                   -->
        <!--  If a source jar is available, it will get pulled in automatically!!!       -->
        <!--  As this is done by (naming) convention of all jars, in a Maven repository  -->
        <dependency>
            <groupId>com.x.y.thirdparty</groupId>
            <artifactId>thirdparty</artifactId>
            <version>1.0</version>
        </dependency>
    </dependencies>

</project>

备注：新项目扩展第三方家长POM的罕见情况是新项目是第三方项目的某种扩展/插件。然后，它可以使用相同的Maven插件版本，dependecies等，如第3方使用。新的扩展/插件与第三方软件的其他部分配合良好，这是最蠢的。
