The importProject task, by default, always tries to fix all JARs inside a project. However, there is an optional flag, "fixJarsBeforeImport", indicating whether to fix the JARs. When set to "false", the script will skip fixing JARs in importProject task. The default is "true".
If the project and JAR files are generated using TIBCO ActiveMatrix Service Grid 3.3.0 workspace, then you can skip this default behavior by setting fixJarsBeforeImport=false for each sds.importProject .
Below is an example:
<target name="importProject">
<sds.importProject projectLoc="${abs_path_to_project_com.sample.tahjs}" fixJarsBeforeImport="false"/>
<sds.importProject projectLoc="${abs_path_to_project_tahjs}" fixJarsBeforeImport="false"/>
</target>
