SapJco 3.0.11 with Maven: It is not allowed to rename or repackage the original archive “sapjco3.jar”

Question

The current version of the sap jco connector enforces the name of the containing jar at runtime. This will lead to exceptions, if it doesn\'t match the name (sapjco3.jar). <

Answer 1

I had the same issue, and below is how I fixed it (in short work around it): 1. Run the command in command prompt

mvn install:install-file 
-Dfile=sapjco3.jar 
-DgroupId=com.company.sap 
-DartifactId=com.sap.conn.jco.sapjco 
-Dversion=1.0 
-Dpackaging=jar

2. This will create a local artifact, or you can also create it in remote repository

3. Download this dependency from maven as shown below:

   <dependency> <groupId>com.company.sap</groupId> <artifactId>com.sap.conn.jco.sapjco</artifactId> <version>1.0</version> </dependency>

This work around would avoid the sapjco3 error:

if (!jarname.equals("sapjco3.jar") 
&& !jarname.startsWith("com.sap.conn.jco") 
&& !jarname.equals("sapjco3_IDE.jar") 
&& Package.getPackage("org.apache.maven.surefire.booter") == null 
&& Package.getPackage("org.eclipse.jdt.internal.junit.runner") == null) {
    throw new ExceptionInInitializerError("Illegal JCo archive \"" + jarname + "\". It is not allowed to rename or repackage the original archive \"" + "sapjco3.jar" + "\".");
}
