Invalid keystore format and ‘keytool genkey’ issues during Jar signing
I have been working on creating keystores and signing jars today, and have run into some interesting finding, and some interesting but obscure errors during this process.
I have the following maven plugin that I wanted to use to sign my jar with my keystore certificate:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>${plugin-jar-version}</version>
<executions>
<execution>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
<configuration>
<keystore>src/main/keystore</keystore>
<alias>3166_javaee</alias>
<storepass>3166_javaee</storepass>
<signedjar>${project.build.directory}/signed/${project.build.finalName}.jar</signedjar>
<verify>true</verify>
</configuration>
</plugin>
Running this maven command:
mvn clean install -e
Before I created the keystore.
Then I run the jar signing with a missing keystore, then I get the following error:

I tried to regenerate the keystore then run the signing manually, only to get the following error:
C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02>keytool -genkey -alias 3166_javaee -keyalg RSA -keystore src/main/keystore/signing-jar.keystore -storepass 3166_javaee -keypass 316 6_javaee -dname "CN=domain" C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02>C:\usr\bin\Java\jdk1.6.0_23\jre\..\bin\jarsigner.exe -keystore src/main/keystore -storepass 3166_javaee -signedjar C:\usr\SYNCH\PACK T\3166\Chapters_Code\ch02\target\signed\chapter02-1.0.2.jar C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02\target\chapter02-1.0.2.jar 3166_javaee jarsigner error: java.lang.RuntimeException: keystore load: Invalid keystore format
Now I have searched around to try to track down what this error actually is, and I have found that the error is because of the keystore path.
if I use the full keystore location ‘src/main/keystore/signing-jar.keystore’ I am able to successfully sign my jar:
C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02>C:\usr\bin\Java\jdk1.6.0_23\jre\..\bin\jarsigner.exe -keystore src/main/keystore/signing-jar.keystore -storepass 3166_javaee -signed jar C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02\target\signed\chapter02-1.0.2.jar C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch02\target\chapter02-1.0.2.jar 3166_javaee Warning: The signer certificate will expire within six months.
Glad to have this solved.
