我正在使用 maven shade 插件为我的项目生成一个合并 jar。 jar 按预期生成，当我尝试使用 jar 并运行它时，我得到一个

java.lang.SecurityException: Invalid signature file digest for Manifest main attributes error.

我用谷歌搜索了上面的错误消息，许多人建议从 META-INF 目录中排除 list 签名。因此，我已经包含了从目录中排除这些文件的步骤 [我看到两个名为 JARSIGN_.RSA 和 JARSIGN_.SF 的文件]，但出于某些奇怪的原因， maven shade 插件无法从 META-INF 目录中排除这些文件。谁能解释我可能做错了什么？我的 pom.xml 在下面，我用来生成 jar 的命令是:

mvn clean package shade:shade

最佳答案

使用 shade 插件 3.2.1，以下对我有用。

<!-- language: lang-xml -->
<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.2.1</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <filters>
                        <filter>
                            <artifact>*:*</artifact>
                            <excludes>
                                <exclude>META-INF/*.SF</exclude>
                                <exclude>META-INF/*.DSA</exclude>
                                <exclude>META-INF/*.RSA</exclude>
                            </excludes>
                        </filter>
                    </filters>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

在插件的文档页面 ( https://maven.apache.org/plugins/maven-shade-plugin/examples/includes-excludes.html ) 整个 <configuration> block 显示在 <execution> 内标签。这是行不通的。 <configuration> block 应该在 <executions> 之外标记如上所示。

关于java - Maven shade插件不排除manifest签名文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34738653/
