I'm creating an uberjar with
build=> (b/uber {:class-dir class-dir
:uber-file "uberjar.jar"
:basis basis})
This throws an error
build=> (b/uber {:class-dir class-dir
:uber-file "uberjar.jar"
:basis basis})

This error is actually thrown from two libs on our classpath:
- .m2/repository/xml-apis/xml-apis/1.4.01/xml-apis-1.4.01.jar
- .m2/repository/xml-apis/xml-apis-ext/1.3.04/xml-apis-ext-1.3.04.jar
Each of these has an entry license/LICENSE. The problem seems to arise that I am on osx which uses a case insensitive but case-preserving filesystem and there is already a top-level LICENSE file from another jar. So it cannot create a license/LICENSE entry in addition to a LICENSE file that already exists.
I repod this with the following code that creates a few jars:
(ns build
(:require [clojure.tools.build.api :as b]))
;; create a jar with just a single namespace and a license/LICENSE file
(b/write-file {:path "target/liba/a.clj"
:content (symbol "(ns a)")})
(b/write-file {:path "target/liba/license/LICENSE"
:content (symbol "this is the license from a")})
(b/write-file {:path "target/liba/deps.edn"
:content '{:paths ["."]}})
(b/write-pom {:basis (b/create-basis {:project "target/liba/deps.edn"})
:class-dir "target/liba"
:lib 'liba/liba
:version "1.0.0"
:src-dirs ["target/liba"]})
(b/jar {:class-dir "target/liba"
:jar-file "target/jars/liba.jar"})
;; create another jar libb with just a single ns and a license file
(b/write-file {:path "target/libb/b.clj"
:content (symbol "(ns b)")})
(b/write-file {:path "target/libb/license"
:content (symbol "this is the license from b")})
(b/write-file {:path "target/libb/deps.edn"
:content '{:paths ["."]}})
(b/write-pom {:basis (b/create-basis {:project "target/libb/deps.edn"})
:class-dir "target/libb"
:lib 'libb/libb
:version "1.0.0"
:src-dirs ["target/libb"]})
(b/jar {:class-dir "target/libb"
:jar-file "target/jars/libb.jar"})
;; create a consumer of these
(b/write-file {:path "target/libc/license"
:content (symbol "this is the license from c")})
(b/write-file {:path "target/libc/deps.edn"
:content '{:deps {liba/liba {:local/root "../jars/liba.jar"}
libb/libb {:local/root "../jars/libb.jar"}}}})
(def old-project-root b/*project-root*)
(b/set-project-root! "target/libc")
#_(b/set-project-root! old-project-root)
(b/uber {:class-dir "."
:uber-file "uberjar.jar"
:basis (b/create-basis {:project "deps.edn"})
:main 'clojure.main})
But the basic error happens when trying to explode the jars and creating a folder license when a file LICENSE already exists.
EDIT
Sean mentioned that depstar has an api-compatible uber function and that has worked for me. Since the contents of the jars never hit the filesystem this constraint is avoided.
