This mostly affects options that use > {{System.getProperty("java.io.tmpdir")}}, as for example > {{CoreOptions#TMP_DIRS}}. > To deal with this the generator has a special branch for selected options > that overrides this default: > {code} > if (option == WebOptions.TMP_DIR || option.key().equals("python.dc.tmp.dir") > || option == CoreOptions.TMP_DIRS) { > defaultValue = null; > } > {code} > (let's ignore for now that it just wipes the default and isn't setting it to > "System.getProperty("java.io.tmpdir")") > This is pretty much hidden deep in the implementation of the generator. It > would be better if we had a dedicated annotation > {{@OverrideDocumentedDefault(String override)}} that options could be > annotated with. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
