Lukasz Gajowy updated BEAM-8024:
--------------------------------
Description:
This was suggested on the devlist in a [thread about Java 11
compatibility|https://lists.apache.org/thread.html/065e7cb9f25a4312ce5f0045ee2946c1d93c04615e37351f1e25a9b8@%3Cdev.beam.apache.org%3E].
I confirmed it in my sandbox project. Source code:
[https://github.com/lgajowy/beamJava11Compatibility]
When building this sample project and importing 3 beam dependencies:
{code:java}
dependencies {
compile group: 'org.apache.beam', name: 'beam-sdks-java-core', version:
'2.14.0'
compile group: 'org.apache.beam', name: 'beam-runners-direct-java', version:
'2.14.0'
compile group: 'org.apache.beam', name:
'beam-sdks-java-extensions-google-cloud-platform-core', version: '2.14.0'
} {code}
It is impossible to compile the project due to split-package problems:
{code:java}
error: the unnamed module reads package com.google.common.flogger from both
flogger and google.extensions
error: module beam.sdks.java.extensions.google.cloud.platform.core reads
package com.google.common.flogger from both flogger and google.extensions
error: module beam.model.pipeline reads package com.google.common.flogger from
both flogger and google.extensions
error: module beam.model.job.management reads package com.google.common.flogger
from both flogger and google.extensions
error: module beam.vendor.guava.20.0 reads package com.google.common.flogger
from both flogger and google.extensions
error: module com.fasterxml.jackson.databind reads package
com.google.common.flogger from both flogger and google.extensions
error: module google.auth.library.oauth2.http reads package
com.google.common.flogger from both flogger and google.extensions
error: module google.api.services.cloudresourcemanager.v1.rev20181015 reads
package com.google.common.flogger from both flogger and google.extensions
error: module gcsio reads package com.google.common.flogger from both flogger
and google.extensions
error: module util reads package com.google.common.flogger from both flogger
and google.extensions
...{code}
as stated in the devlist thread, more dependencies can cause problems.
