| [tycho-user] Bug? mvn dependency:tree approximate of dependencies wrong |
Hi, I my build, there are two versions of bundle com.google.guava: 15.0.0 and 21.0.0. Now, one of my plugins has > Import-Package: com.google.common.base;version="[15.0.0,16.0.0)" in its MANIFEST.MF. During compilation, this works fine. It sees version 15.0.0 of com.google.guava (which exports the above package). During a "mvn dependency:tree" however, Maven lists (only) Guava 21.0.0 as a dependency: > [INFO] ------------------------------------------------------------------------ > [INFO] Building org.eclipse.epp.logging.aeri.ide 2.0.3-SNAPSHOT > [INFO] ------------------------------------------------------------------------ > [INFO] > [INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ org.eclipse.epp.logging.aeri.ide --- > [INFO] org.eclipse.epp.logging:org.eclipse.epp.logging.aeri.ide:eclipse-plugin:2.0.3-SNAPSHOT > [INFO] +- p2.eclipse-plugin:com.google.guava:jar:21.0.0.v20170206-1425:system Apparently, one of org.eclipse.epp.logging.aeri.ide's own dependencies pulls in Guava 21.0.0 transitively. The resulting discrepancy between the OSGi world and Tycho's approximation of the rest of the world causes other plugins, like the animal-sniffer-maven-plugin, to become confused: > [INFO] --- animal-sniffer-maven-plugin:1.15:check (check-signature) @ org.eclipse.epp.logging.aeri.ide --- > [INFO] Checking unresolved references to org.codehaus.mojo.signature:java18:1.0 > [ERROR] /tmp/org.eclipse.epp.logging/bundles/org.eclipse.epp.logging.aeri.ide/src/org/eclipse/epp/internal/logging/aeri/ide/utils/Zips.java:56: Undefined reference: Object com.google.common.io.OutputSupplier.getOutput() > [ERROR] /tmp/org.eclipse.epp.logging/git/org.eclipse.epp.logging/bundles/org.eclipse.epp.logging.aeri.ide/src/org/eclipse/epp/internal/logging/aeri/ide/server/json/Json.java:152: Undefined reference: Object com.google.common.io.InputSupplier.getInput() Guava 15.0.0 contains OutputSupplier.getOutput() and InputSupplier.getInput(), but apparently the animal-sniffer-maven-plugin is looking at the wrong version, namely Guava 21.0.0. Is this a bug with Tycho 1.0.0? I would think so, as being able to use non-Tycho Maven plugins like animal-sniffer-maven-plugin seems like a huge win (and so far has worked fine).
