maven bouncycastle jar java.lang.SecurityException

 

Use maven-shade-plugin to package the runnable jar, but because the bouncycastle related jar is referenced, an exception "java.lang.SecurityException: no manifest section for signature file entry" occurs after the packaged jar is run.

 

After google for a long time, I found that due to the jar related to bouncycastle, the general maven-shad-plugin configuration is not available. It needs to be modified and added as follows:

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
				<version>${maven.shade.plugin.version}</version>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>shade</goal>
						</goals>
						<configuration>
							<!-- because no manifest section for signature file entry -->
							<filters>
								<filter>
									<artifact>*:*</artifact>
									<excludes>
										<exclude>META-INF/*.SF</exclude>
										<exclude>META-INF/*.DSA</exclude>
										<exclude>META-INF/*.RSA</exclude>
									</excludes>
								</filter>
							</filters>

							<transformers>
								<transformer
									implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
									<mainClass>com.csair.jar.Provider</mainClass>
								</transformer>
								<transformer
									implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
									<resource>META-INF/spring.handlers</resource>
								</transformer>
								<transformer
									implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
									<resource>META-INF/spring.schemas</resource>
								</transformer>
							</transformers>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
