我在部署由 maven-shade-plugin 创建的 jar 文件时遇到问题。它曾经工作，但它已经停止工作。根据我的研究，问题似乎是安装步骤正在覆盖阴影 jar。

如果我使用以下设置：

<shadedArtifactAttached>true</shadedArtifactAttached>

它会为我创建一个胖罐子，但如果我把它改成

<shadedArtifactAttached>false</shadedArtifactAttached>

安装/部署将删除主类的依赖项和清单条目。

我不想使用“true”设置，因为文件重命名会破坏我所有依赖于通用脚本的工具，该通用脚本将通过 cURL 部署工件。

所以，当我跑步时

$ mvn -s ../.m2/settings.xml --batch-mode --errors --fail-at-end --show-version clean package shade:shade

我得到正确的文件：（ontology-merger-0.3.31.jar大文件）和original-ontology-merger-0.3.31（小文件）

当我跑步时

$ mvn -s ../.m2/settings.xml --batch-mode --errors --fail-at-end --show-version clean package shade:shade install

安装步骤将丢弃阴影 jar。我假设发生这种情况是因为它正在运行maven-jar-plugin它，尽管我没有提到maven-jar-plugin我的pom.xml. 我不知道如何关闭它。

我pom.xml目前的部分如下所示：

                                <!-- Some jars are signed but shading breaks that. Don't include 
                                    signing files. -->

我的各种修复尝试都在这个分支中：

https://gitlab.com/allotrope-open-source/ontology-qa-tools/-/tree/deployment-test

pom.xml 的路径：

https://gitlab.com/allotrope-open-source/ontology-qa-tools/-/blob/deployment-test/merger/pom.xml

一点历史：

我的部署已经运行了多年而没有出现问题，最近我已经崩溃了，我上个月通过

https://gitlab.com/allotrope-open-source/ontology-qa-tools/-/commit/7080d16179c2ccf7ab47208716b1bf1b3a05be29

和

https://gitlab.com/allotrope-open-source/ontology-qa-tools/-/commit/0d231d691ffd48347e34f9da9373d092939e69e2

我必须在pom.xml文件中添加一些样板并进行更改

$ mvn -s ../.m2/settings.xml --batch-mode --errors --fail-at-end --show-version clean deploy

至

$ mvn -s ../.m2/settings.xml --batch-mode --errors --fail-at-end --show-version clean package shade:shade deploy

谢谢你的时间

我找到了解决方案。将此添加到pom-xml：

<plugin>
    <groupId>maven</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
        </execution>
    </executions>
</plugin>

这会将 的执行maven-jar-plugin从install阶段转移到package阶段，因此它将不再破坏maven-shade-plugin. 然后可以通过调用来完成部署：

mvn clean package shade:shade deploy
