For instructions on building Apache UIMA please refer to: http://incubator.apache.org/uima/svn.html#building.with.maven If you have installed both the Apache UIMA binary distribution and the Apache UIMA source distribution, you can run the addSourceJars.bat (or .sh) script to add the source code to the jar files in the UIMA_HOME/lib directory. This may make it more convenient to access the UIMA Source Code (and JavaDocs) from an IDE such as Eclipse. See the NOTICE file for licensing information. Apache UIMA is an effort undergoing incubation at The Apache Software Foundation (ASF). Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
