从依赖于其他项目的maven项目构建jar

Question

我在eclipse中有一个名为abc的spring项目。我需要创建一个项目的罐子。这个项目依赖于abc-lt-核心。我无法控制这种依赖

<dependency>
    <groupId>com.abc.lt</groupId>
    <artifactId>abc-lt-core</artifactId>
    <version>5.1.4</version>
</dependency>

abc-主叫者

在构建maven项目时，我得到以下错误

Answer 1

您的问题不在于您的项目，而在于依赖项目的POM。

您所得到的错误是告诉您，URL/路径上有一个非法字符，它阻止Maven解决依赖关系。

未能读取com.abc.lt:abc-lt-core:jar:5.1.4:未能将工件com.abc.lt:abc:pom：${masterVersionNumber}从/转到中心(http://repo.maven.apache.org/maven2)：索引71: http://repo.maven.apache.org/maven2/com/abc/lt/abc-lt/ -> Help 1路径中的非法字符

请看粗体文字。它没有解析${masterVersionNumber}属性。我怀疑这是部署上的问题。

如果您无法控制它，您可以手动下载JAR并将其安装到本地的m2回购中并以这种方式构建吗？这应该能让你度过难关直到修好为止。

如果需要使用依赖关系创建jar，则可以使用maven-程序集-插件的单个目标。

...

<build>
...
    <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>

                        <mainClass>MAIN_CLASS</mainClass>
                    </manifest>
                </archive>
                <!-- <finalName>JAR_NAME/finalName> -->
                <descriptorRefs>

                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
    </plugin>
...
</build>
...

这个插件被添加到maven生命周期(<phase>package</phase>)的打包阶段。jar与依赖关系生成一个只包含所有依赖项的jar。
